Stage 1 Sleep
Stage 1 sleep
The correct order for the sleep stages is as follows: Stage 1 (light sleep), Stage 2 (light sleep with sleep spindles), Stage 3 (deep sleep), and REM (rapid eye movement) sleep. A typical sleep cycle progresses through these stages in that sequence, with REM sleep occurring after deep sleep. This cycle repeats several times throughout the night, with each cycle lasting about 90 minutes.
The deepest stage of sleep is REM or Rapid Eye Movement.
There is alpha or stage one sleep, theta or stage two sleep, delta or statge 3 sleep, and alpha with REM (stage 4 sleep).
You return to stage 3, then stage 2 (delta sleep) before going to REM sleep (stage 5).
You return to stage 3, then stage 2 (delta sleep) before going to REM sleep (stage 5).
You return to stage 3, then stage 2 (delta sleep) before going to REM sleep (stage 5).
Stage 1, then 2, then 3, then 4, then REM, then back to 4, 3, 2, 1...
3,4. Both stages are now combined and are just called stage 3, SWS ( slow wave sleep) or deep sleep. Stage 3 is the deepest stage.
Delta sleep is the first sleep to be made up after sleep has been lost. Stage 4 sleep.
stage 2 sleep
hyperthermia, confusion, breathing difficulty, coma, death. Lesser symptoms can also include temporal, latency visual hallucinations; especially when awaking from sleep during minor serotonin toxicity or "over-drive".

I have personally experienced this. It is like dreaming with your eyes open.
