Visions, Lucid Dreaming, muscle spasms, and Hallucinations when high

I have this issue when I smoke weed, I am a beginner and I could count the amount of times I've gotten high on one hand. Every time I get high I feel like I am in a dream where I don't comprehend information normally and everything feels very fake and artificial. I don't know what I am thinking or have any control over my thoughts. When I close my eyes I see the universe, stars, galaxies, images and events from my childhood that I have long forgotten. It's like it taps into the long-term memory section of my brain and brings memories and images back from being long forgotten. I also see things I've never seen before. It scares me more then a little. My pulse goes through the roof, I start to shake, and my muscles flex and unflex without my control like I am having a seizure, my face gets really hot like I have a fever. This is not the worst part however, it's when I go to sleep, I start to lucid dream, I see events from the past and I am a bystander, not in my body, often staring at myself from a distance, or from the corner of the room. I see events that happen in the future too, sometimes from the next time I am high. For example I once saw a police officer parked outside my house walking around it with a flashlight looking through our windows. The next time I was high (a few weeks later) my cousin and I fell asleep watching TV, I accidentally activated the motion sensor and I woke up and the alarm went off when I stood up. A few minutes later police came to the house with flashlights seeing if we we ok. After we told the police everything was ok, I told my cousin about the vision and he told me to fuck off because he thought I was pulling his leg. I don't know what's wrong with me and no the weed was not laced, I've purchased from 3 different dealers and i've had the same reaction to all of their weed. Any explanation would help.
