Yeah. Aside from a deep long depression, delusions first came after an awakening experience of suddenly seeing a lot more, my vision just expanded, which happened a few days after an already intense mushroom trip. This made the 16 year old insecure me feeling like I might be better than others, that I might be the chosen one, which eventually led into fear, where I thought that just rather random things meant serious stuff. Wanting to belief I was enlightened.
Deep down I would I knew these things to be untrue, but when you are so caught up in your ego, carrying around a lot of fear, you go tend to (want to go) with it.
