Mescaline has given me time dialation to the point of time slipping/fragmentation, that soon manifested as basically time travel.
I experienced time breaking down into frames, with each frame stacking, or overlapping previous and future frames. Each frame from either the future or the past began to take on a life of its own as well, and communicating with the present frame or "me", seemingly reaching out across time. It was very frightening and I thought I was ging to be commited to be honest. I took off into the bush leaving all my friends behind and spent many hours alone, walking non-stop. I walked a far distance through the city following the ocean, time traveling and periodically stopping a different beaches to try to get ahold of myslef.
Cannabis had a played a large role though. Cannabis in high doses facilitates time distortion and time travel for me. I had smoked cannabis about 6 hours after I started consuming the cacti, and I hadn't had it in many weeks prior so there was no tolerance.
The same thing happened to me about 2 months ago after drinking 80g of caapi. I thought the caapi was basically finished with me after about 3 hours so I walked to the beach wth minxx and we smoked. I took one large hit and that was it. It was so much like that time with cacti, just a little less intense.
I dont get near cannabis with other entheogens anymore.
