Other conditions, such as hypothalamic hamartoma HH , can cause gelastic seizures. These are bouts of uncontrolled laughter or giggling. They can happen at any time but often occur as the person is falling asleep. HH is congenital, meaning that people are born with it. The average age of onset is around 10 months.
Gelastic seizures can happen many times per day and last around 10—20 seconds. They may start with a butterfly-type sensation in the tummy, a tickling in the chest, or a headache. The person might look startled or scared and exhibit automatic behaviors such as lip smacking or swallowing before the seizure starts. Babies often laugh in their sleep. Experts do not fully understand why, but it is very common and not usually anything to worry about.
In fact, many parenting websites talk about the joy of hearing babies giggle while sleeping. In very rare cases, it might be a symptom of an underlying health condition.
A cause for concern may be if the baby is having several uncontrollable bouts of laughter throughout the day accompanied by other unusual behaviors, such as those detailed above. Laughing during sleep is common in adults and babies alike.
Among adults, the most common cause is amusement in a dream. The cause is unclear in babies, but it is usually not anything to worry about. Sometimes, the laughter may be a symptom of the sleep disorder RBD, during which people act out their dreams. These movements include cramping and jerking and often involve restlessness and disturbed sleeping patterns.

Sleep talking or somniloquy is a sleep disorder where a person tends to talk during sleep without being aware of it. However, it can be unpleasant for your partner or any person you share the room with.
Also, it may sound like a typical occurrence. Still, it is essential to have yourself checked once you see the warning signs—this includes laughing associated with wild body movements and laughing while screaming or shouting or exhibiting any abnormal behavior.
Laughing during sleep is not always a positive thing, so be sure to take all the stress away and think of happy thoughts before you sleep.

These episodes are on the shorter side, with most lasting less than an hour. These are more common in children, but they can also happen in adults. An increased risk of parasomnia can be caused by:.
For example, many researchers note that babies may twitch or smile in their sleep during active sleep. When babies go through this type of sleep, their bodies can make involuntary movements. These involuntary movements might contribute to smiles and laughter from babies during this time.
