Answers:

This stage of sleep is called somnolence. 2 guys named Rechtschaffen and Kales initially outlined the criteria for this first stage of sleep as follows:-

the brain transitions from alpha waves (common to people who are awake and having a frequency of 8-13 Hz cycles/second)) to theta waves (frequency of 4-7 Hz). Associated with the onset of sleep during stage 1 may be sudden twitches and hypnic jerks. These are normal. Other people may also experience hypnagogic hallucinations during this stage, which can be more troublesome. During stage 1 the subject loses some muscle tone, and conscious awareness of the external environment.
