Original VAYEMA symptom and impact self-check – not a validated scale
Unusual behaviours during sleep
Answer the symptom statements below to see which experiences and areas of daily life you report as most affected. These are original VAYEMA questions, not a validated diagnostic scale. No clinical severity or probability score is calculated.
Answers are processed only in this page by this assessment. They are not submitted, monitored or automatically saved. No name, email or account is required. Use a private device and clear your answers when finished.
For adults aged 18 and over. This self-check cannot diagnose or rule out a condition. Concerns about a child require an age-appropriate professional assessment.

What a parasomnia assessment is trying to distinguish
Parasomnia is an umbrella term, not a single diagnosis. Sleepwalking, sleep terrors, nightmares and REM sleep behaviour disorder differ in how they occur and how they are managed. Events related to breathing problems, seizures or other conditions can sometimes resemble a parasomnia. The clinician therefore asks about the whole episode rather than identifying it from a dramatic movement or a frightening dream alone. [1]
Begin with the concern that matters most: injury, fear of sleeping, disturbing a partner or uncertainty about something you cannot remember. You do not need to know which sleep stage was involved. Our understanding parasomnias guide explains the background. A specialist assessment connects that information to your actual history and determines which questions need investigation.
Describe the event before choosing a label
Useful details include what the person did, whether their eyes were open, whether they responded, and what happened before they settled or woke. State approximately how long the event lasted and whether episodes look similar each time. Separate observation from interpretation: saying that someone shouted and moved their arms is different from concluding that they experienced a nightmare, seizure or remembered trauma.
A short representative account is usually easier to work with than a large collection of uncertain interpretations. Describe what you genuinely recall, including gaps. You do not have to recreate the event or test whether a particular noise or interruption triggers it. When someone else witnessed it, identify which details come from them rather than combining both accounts into an apparently certain narrative.
Timing and recall help, but do not diagnose the event
A clinician may ask whether events occur soon after falling asleep, later in the night or during waking. They may also ask whether there is dream recall or confusion afterwards. Sleepwalking and sleep terrors often have a different pattern of recall from nightmares, but timing and memory are clues rather than stand-alone diagnostic rules. People may have more than one kind of night-time difficulty. [2]
You can use approximate times without repeatedly checking the clock. For example, ‘about an hour after going to bed’ may be enough to begin the discussion. Record uncertainty when a partner was also partly asleep. The goal is useful context, not perfect surveillance. If detailed recording makes everyone more anxious or reduces sleep, ask the clinician for a simpler way to provide information.
Injury and dream enactment deserve specific attention
Report falls, leaving the bedroom, striking a partner, reaching a window or handling objects during an episode. These details help the professional address safety while clarifying the diagnosis. Dream enactment can warrant assessment for REM sleep behaviour disorder, which has different implications from ordinary sleep talking. A clinician may recommend an overnight study and, where appropriate, neurological evaluation. [3]
Ask for advice suited to your home rather than improvise restrictive measures. Do not lock someone into a room, block emergency exits or restrain them as an informal treatment. If an episode causes serious injury or an immediate threat, urgent help takes priority. Later, discuss how you and anyone sharing the room can sleep more safely without expecting a partner to provide continuous overnight observation.
Review medicines, substances and other sleep symptoms
Bring a current medication list, including non-prescription products and recent changes. Describe alcohol and other substance use accurately, without changing the account to fit a presumed explanation. Sleep deprivation, illness and medication effects can be relevant, and the clinician may also ask about snoring, breathing pauses and daytime sleepiness. A previous psychiatric diagnosis should not lead everyone to assume that the event is psychological. [2]
Do not stop prescribed treatment or take additional sleeping tablets to experiment before the appointment. Explain what you have already tried and whether anything changed. This allows the prescriber and sleep clinician to coordinate a review. An accurate partial list is preferable to an elaborate explanation built around one suspected cause. When a medicine is involved, the appropriate response depends on its purpose, risks and alternatives.
When an overnight sleep study may be useful
Not every person with sleepwalking needs a laboratory investigation. A specialist may recommend polysomnography, sometimes with video and additional measurements, when the history suggests a condition that needs confirmation or events are unusual, injurious or difficult to distinguish. For suspected REM sleep behaviour disorder, the assessment can examine sleep-related muscle activity alongside the clinical account. [3]
Ask what the test is intended to answer, what preparation is needed and how results will change care. An uneventful night in a sleep laboratory does not automatically settle every intermittent symptom. Interpretation belongs with the clinician who knows the history. Consumer recordings, wearables and apps may supply observations, but they do not independently identify the sleep stage or provide a complete neurological or respiratory assessment.
Using a diary or a recording without creating another risk
A brief diary might include bedtime, approximate waking time, reported events, sleep disruption and daytime effects. Keep the detail proportionate and agree any longer recording period with the clinician. A partner’s voluntary account can be helpful. A home video may occasionally add context, but only when it can be obtained safely and with appropriate consent and privacy; it is not a requirement for getting help.
Do not deliberately wake, startle or sleep-deprive someone to obtain evidence. Do not put cameras in private spaces without agreement or share footage on social media for informal diagnosis. Ask the receiving service how useful material can be transferred securely. This website’s preparation tool does not accept video, analyse movements or identify a condition from text. Its only purpose is organising your own observations.
The impact on a partner or family belongs in the discussion
Night-time events can affect more than the person experiencing them. A partner may be frightened, repeatedly woken or unsure how to respond. Ask what to do during an event and what should trigger medical contact. The AASM guidance on REM sleep behaviour disorder emphasises reducing injury risk in the sleep environment, with individual recommendations rather than an assumption that everyone can safely continue sharing a bed. [4]
A family member can support the assessment without becoming responsible for diagnosis or medication. Discuss whose account is recorded and what information is shared. If relationships have become strained by lost sleep, family support can address communication and practical needs. It should complement the appropriate sleep or medical assessment, not replace investigation of potentially dangerous events.
What a useful assessment conclusion should contain
Ask for the working explanation, important alternatives, any tests recommended and a practical safety plan. The clinician should explain whether the next step is observation, treatment of another sleep problem, medication review or referral to a specialist service. Uncertainty is acceptable when it is accompanied by a clear plan for resolving it. Simply naming parasomnia does not explain what you should do next.
Our parasomnia treatment guide describes the different roles of medical and supportive care. Confirm who will review results, arrange follow-up and respond if events change. VAYEMA can discuss a private assessment and suitable referral, but an educational page does not establish that a sleep laboratory or every neurological service is available within the clinic.
When not to wait for a planned appointment
Serious injury, difficulty breathing, prolonged unresponsiveness, a suspected seizure or new severe confusion needs appropriate urgent medical care. Do not assume that a familiar history of sleepwalking explains a substantially different event. An inability to stay awake safely during the day also deserves attention. Avoid driving or hazardous tasks when sleepy; the worksheet cannot clear you to continue them.
The notes remain an optional aid for a non-emergency conversation. Entries are not sent to VAYEMA, monitored or automatically added to a patient record. A file you deliberately download remains on your device and should be stored privately. You can attend with a spoken account instead. Seek the right professional help first when there is an urgent concern; gathering information should never postpone necessary care.
Frequently asked questions about parasomnia assessment
Can an online parasomnia test identify which condition I have?
No. Similar behaviours can have different explanations. The prompts on this page are unscored and cannot identify a sleep stage, diagnose a disorder or assess safety. A professional combines the event description with health history and, when needed, specialist investigations.
Do I need to remember what happened?
No. Limited recall can be part of the reason for assessment. Explain what you remember and which information comes from someone else. Do not invent missing details. A clinician can work with uncertainty and decide whether further observations or tests would help.
Will I definitely need an overnight sleep study?
Not necessarily. The decision depends on the suspected condition, event pattern and safety concerns. Ask which question the test would answer. A routine diary, questionnaire or consumer device is not interchangeable with a specialist sleep study.
Should my partner record every episode?
No continuous monitoring is required by this worksheet. A brief voluntary account may be useful, while safe recordings can sometimes be discussed with the clinician. Do not provoke an episode, sacrifice sleep or use recording that compromises privacy or safety.
Can stress explain all unusual sleep behaviour?
Stress may be relevant, but it should not be used to dismiss other sleep, medical or medication-related explanations. New, injurious or substantially changed events deserve assessment. Psychological support and medical investigation can both be appropriate without assuming one explanation in advance.
Does entering a safety concern notify a clinician?
No. The tool does not send information or create alerts. Contact the appropriate medical or emergency service directly when needed. Your notes are only a preparation aid for an appointment and do not provide crisis monitoring or a diagnosis.
