Sleep paralysis typically occurs during the stage of sleep known as REM (rapid eye movement) sleep.
The rhythmic bursts of brain activity that occur during Stage 2 sleep are called sleep spindles. These are short bursts of brain waves that help in the consolidation of memories and are characteristic of this stage of sleep.

There are 4 stages of sleep: Stage 1, Stage 2, Slow wave sleep, and REM. The stages occur in that order. Stage 1 occurs as you are falling asleep, and REM occurs last and contains the craziest dreams. REM is the most difficult to awaken from, so it is likely the stage that you have heard referred to as 'deep sleep'.
Bedwetting, or nocturnal enuresis, is most likely to occur during Stage 3 or Stage 4 of non-REM sleep, which is deep sleep. During these stages, the brain may not respond to signals from the bladder indicating the need to urinate, leading to involuntary bedwetting.
Snoring typically occurs during the deeper stages of sleep, known as REM (rapid eye movement) sleep.
A nightmare is one of those dreams where, when you wake up, you thing "Oh, thank goodness. It was only a dream." Then you roll over and go back to sleep. Night terrors are dreams so vivid that you wake up thinking that the incident actually occurred, and may continue to think so until you are fully awake. Most people have them once or twice a year. If you are having night terrors regularly, you need to consult a professional and get some counseling. Frequent sleep disruptions are extremely bad for your physical and emotional health. Whatever you do, don't drink or take sleeping medications to avoid them. They do nothing to correct the underlying problem, and you will become dependent on the booze or meds to help you sleep, just adding another layer of problems.
Nightmares and sleepwalking are both examples of parasomnias, which are abnormal behaviors or experiences that occur during sleep. Nightmares involve vivid and disturbing dreams that can cause distress and awaken the sleeper, while sleepwalking entails performing complex behaviors while still asleep, often without any memory of the event upon waking. Both phenomena highlight the complexities of sleep and the brain's activity during different sleep stages.
