Your partner's dream enactment and striking the bedside table may be REM sleep behavior disorder, or RBD. In RBD, normal REM-sleep muscle relaxation is lost, allowing a person to physically act out dreams, but the behavior alone does not confirm the diagnosis. RBD is strongly associated with Parkinson's disease. The Parkinson's Foundation reports that nearly half of people with Parkinson's describe RBD symptoms, which can include yelling, punching, kicking, jumping, or falling from bed in its sleep-disorders briefing.

Why does this happen during dreams?
Most muscles normally remain relaxed during REM sleep, the stage commonly associated with vivid dreams. With RBD, that protective relaxation does not work normally, so dream-related movements can reach the waking world. An episode might involve talking or shouting, swinging an arm, kicking, or making a larger movement out of bed.
Hitting the bedside table fits this pattern, but similar-looking events can have other causes. Dream enactment can begin years before a Parkinson's diagnosis. In someone already diagnosed, it may appear before, alongside, or after motor symptoms.
How is suspected RBD diagnosed?
Tell the clinician exactly what happens, how often it occurs, and whether either partner has been hurt. Your observations matter because the sleeping person may not remember the movements.
A sleep clinician can combine that history with video-polysomnography, an overnight sleep study that records movement and other body signals. The International RBD Study Group says this testing is essential for diagnosis and helps distinguish RBD from conditions such as sleep apnea and non-REM parasomnias in its diagnostic guideline. Before the appointment, record details when you can do so safely:.

Make the bedroom safer now
Do not wait for a confirmed diagnosis before reducing injury risks. Both the sleeping person and the bed partner can be struck, cut, or hurt during a fall.
The American Academy of Sleep Medicine recommends practical bedroom changes in its RBD safety guidance: These changes address the immediate danger, not the underlying sleep disorder. Continue pursuing a clinical evaluation even if moving the furniture prevents another injury.
- Remove the bedside table or move it beyond striking distance.
- Take away hazardous objects near the bed.
- Pad or reposition furniture with sharp edges.
- Place cushioning on the floor beside the bed.
- Sleep separately when episodes are severe, at least until treatment controls them.
What treatments might the clinician discuss?
For RBD related to a medical condition such as Parkinson's, the American Academy of Sleep Medicine conditionally suggests immediate-release melatonin or clonazepam in its 2023 clinical guideline. "Conditionally" means neither medication is automatically right for every person; the choice should reflect individual risks and circumstances. Clonazepam may improve RBD symptoms, but it can cause sedation, dizziness, cognitive effects, or postural instability.
It requires particular caution in older adults and people with gait problems, dementia, or obstructive sleep apnea. Ask the Parkinson's clinician or a sleep specialist to weigh treatment against fall risk, thinking changes, and possible sleep apnea. Until that review occurs, remove the bedside table and other hard or sharp objects within reach.
