When i smoke alot of a sativa strain i often get some hallucination outside at night, and i definately get CEV's, and i'll get auditory hallucinations randomly which are quite vivid, some weed doesn't get me hallucinating as much, although one must note that when i smoke it's late at night and im already very tired so adding the weed to it makes me EXTREMELY tired, therefore i'm way more prone to hallucinations, but some sativa strains are more likely to cause hallucinations i know that, try some Neville's Haze or other haze's are known for trippy highs
