I had it for years. It was a traumatic experience at first, but eventually, I got used to it. Despite being harmless, the majority of people consider it a nightmarish experience to cope with.

Sexsomnia Sexsomnia, also known as sleep sex, is a sleep disorder in which a person engages in sexual activity while asleep. It is a type of parasomnia and can occur during any stage of sleep, including non-REM and REM sleep. People with sexsomnia may not be aware of their actions and may have no memory of the episode upon waking.
REM Behavior Disorder REM behavior disorder (RBD) is a sleep disorder characterized by the loss of muscle atonia during REM sleep, resulting in the person acting out their dreams. This can include talking, yelling, punching, or kicking, and can be dangerous to the person or their sleeping partner. RBD is often associated with other neurological disorders such as Parkinson's disease.
Night Terrors Night terrors, also known as sleep terrors, are a type of parasomnia that occurs during non-REM sleep. They are characterized by intense fear, screaming, and thrashing, and can last from a few minutes to half an hour. Unlike nightmares, people with night terrors are difficult to awaken and may not remember the episode upon waking.
Exploding Head Syndrome Exploding head syndrome is a sleep disorder in which a person experiences a sudden loud noise or explosive sensation in their head while falling asleep or waking up. The sensation is not painful but can be frightening and may cause anxiety and difficulty falling asleep.

During these episodes, people with the syndrome may sleep for up to 20 hours a day and have a reduced ability to function normally. The cause of the syndrome is not fully understood, but it is thought to be related to a malfunction in the hypothalamus, the part of the brain that controls sleep and appetite.
