I woke up this morning, and in the right side of my peripheral vision I saw a small blind spot that was covered with rainbow-like colored patches of lines that were constantly moving in geometric shapes.
I got up and started to walk around, and the colored shapes/lines continued to spread. At the peak of this, about half of the right side of my vision was completely covered. I can't really explain what it looked like, but what I found online that best described it was psychedelic hallucinations from the drug LSD.
The shapes were constantly moving and kept transitioning colors of the rainbow.
Let me first clarify this: I have never used any drugs, nor have I ever drank and alcohol in my life. I'm a 21 year old male.
Can anybody explain to me why I had hallucinations without drugs? This is really disturbing me. This happened to me once in highschool when I was driving home, but never thought anything from it.
