You are very correct, which is why I had to add that Ive never done them before.
Like I said, the closest thing to a psychedelic experience that Ive had is the PCP trip. I also have to add it was an extremely large dose of PCP that I did on accident as my weed was drenched with it, but at the time I knew nothing of PCP. I actually almost ODed, it was that large. It caused me to have mild visual and audio hallucinations, but the most significant part was that I was INCREDIBLY delusional. So although I wouldnt say it was psychedelic, it was definitely something. Not a good trip at all though, much too intense.
Oh yes, and about the high grade marijuana. Although not psychedelic, Ive had some incredible experiences on just weed. Ive had several amazing stories that Ive told on here about my experiences. One was when I was a mere beginner and smoked 2 large blunts of a powerful Kush strain grown hydro. That along with sleep deprivation and eating barely anything that day. You probably wouldnt believe me, but the trip involved seeing things happen in the future, present, and past right after eachother. Also watching the clock tick so slow it seemed to go backwards, each second seemed like 5 minutes easily. I locked myself in the bathroom and stared in a mirror at only myself for around 30 minutes straight. I achieved a feeling and an understanding that was amazing and Ive never been able to duplicate it. I can only imagine what something like a high dose of LSD, DMT, or Shrooms are like.
