My friend has been waking up on the sound of her own laugh...She seems to wake up laughing so hard, but she doesn't know the cause, can't remember she was dreaming about something. What can that be ?

Sleep laughing falls under "Somniloquy" or sleep talking. It is a type of parasomnia (an abnormal behavior that takes place during sleep). It is is not usually considered a medical problem. Some attribute it to sleep deprivation or to stress.
