Question: what does it mean when you wake up and see spiders?
Answer: Hypnagogic/ Hypnopompic Hallucinations. Vivid dreamlike experiences—called hypnagogic or hypnopompic hallucinations—can seem real and are often frightening. They may be mistaken for nightmares, and they can occur while falling asleep (hypnagogic) or waking up (hypnopompic).
