So I'm sure there has to be an explanation for this, but it's never been explained to me and I've always wondered how 2-3 hours in you can feel completely sober then BAM! Reality is peeling away again, I ask because I had a nice trip in the woods yesterday but about 2-3 hours in I quit tripping completely for about 20 minutes, no visuals or headspace or racing thoughts; I decided it was time to head home but the walk back to my car was where it got even more insane, a vine laying on the ground suddenly turned into a 6 foot long snake as I stepped over it, brought on some anxiety cause it happened so fast and I noticed another passerby on the trails saw me turn around and stare deep into the leaves and sticks on the ground for a good minute. Still I decided I was way past my peak and could drive home, but as I got close to the parking area through the woods I swear I saw at least 5 black chargers with police lights on them so fear shot straight through my body, I was dead, they were going to come cuff me and drag me through the woods to the county jail all while I was halfway into a different dimension. I just laid my blanket I was carrying on the ground and sat lotus style for about an hour with my eyes closed, eventually I completely forgot about the cop hallucination and walked to my car only to find it was a single black charger parked in front of me, no cop. I firmly believe the hallucination was the L telling me to go back into the woods and that there's no way I would've made it home in that state. Sorry to get off topic thought I should share that but back to the point, is there any evidence why lsd hits you in waves of euphoria and visuals while every now and then it completely dissipates for minutes at a time?
