night tripping

Hallucinating after prolonged sleep deprivation. Unlike regular tripping, this is mostly done on accident, sometimes involving too much caffeine, or a sign of insomnia or other sleep disorder.

Hallucinations during night tripping are usually more horrifying in nature, involving shadows and flickering light. Someone may even think they see bugs crawling on the walls, or shadow people.
