Sleep paralysis and vivid dreams can occur while falling asleep or waking up.
Simply put, the brain does not pass through the normal stages of dozing and deep sleep but goes directly into (and out of) rapid eye movement (REM) sleep.
People with narcolepsy may dream even when they only fall asleep for a few seconds.
Does dreaming indicate good sleep?
Research shows that good sleepers often describe their dreams as being more pleasant and joyful, while people who suffer from insomnia tend to have fewer positive emotions associated with their dreams, but whether or not a happy or sad dream means you’ll sleep better or worse still isn’t clear.
Why do I see things in my sleep?

Why do I hallucinate before falling asleep?

They are often associated with a sleep disorder called narcolepsy. These hallucinations are relatively common in teenagers and young adults.
