1.英文答案
A dream is the experience of images, sounds/voices, words, thoughts or sensations during sleep, with the dreamer usually not being able to influence the experience. The scientific discipline of dream research is oneirology. Dreaming has been associated with rapid eye movement (REM) sleep, a lighter form of sleep that occurs during the latter portion of the sleep cycle, characterized by rapid horizontal eye movements, stimulation of the pons, increased respiratory and heart rate, and temporary paralysis of the body; however, this association has been questioned, as it may only be that dream recall is easiest after REM sleep.

Dreaming does occur in other phases of sleep, though dream recall is more difficult. Hypnogogia, which occurs spontaneously during the approach to sleep, is thought to be related to dreaming. Dreams are also associated with male erection about as frequently as with REM sleep.

2.英文答案
Activation Synthesis Theory is a neurobiological theory of dreams, put forward by Allan Hobson and Robert McCarley in 1977, which states that dreams are a random event caused by firing of neurons in the brain. This random firing sends signals to the body's motor systems, but because of a paralysis that occurs during REM sleep, the brain is faced with a paradox. It synthesizes a narrative by drawing on memory systems in an attempt to make sense of what it has experienced.
