Two types of hallucination associated with the sleep/wake process would be hypnagogic and hypnopompic hallucinations; both are false perceptions that occur during the process of either wakefulness to sleep (hypnagogic) or during sleep to wake (hypnopompic). Pretty much what can occur during both is people having either visual or auditory hallucinations, meaning hearing or seeing things that aren’t really there. Sometimes they can be simple hallucinations but other times they are very realistic. I’m not sure if sleep paralysis would be considered a type of hallucination but it does happen in the sleep/wake process as well. During sleep paralysis your body gets a temporary paralysis, while your mind is up and running. For example, you wake up
