"for me it had a lot of hallucinogenic properties that lasted for 3 days. the sleep was solid though. it was when you woke up that the hallucinations began. there were closed-eyed and open-eyed hallucinations. in terms of strength, the closed-eyed hallucinations were vivid and clear, like watching tv. the open-eyed ones were very subtle. they decreased rapidly as you got up. the open-eyed hallucinations were still visible well into the third day. if you concentrated you could make them out. i only took the drug twice. 600mg and 300mg. no difference in intensity between the two but at 300mg the residual effects did not last as long."
