I can post the dozens of DMT "soul surgery" stories and terrifying demonic encounters as well from people who do these things. Like @parker said they give the feeling of epiphanies but in reality it's nothing. I know people will talk about all the positive cases of people improving their lives but honestly at most it sounds like it gets them out of a funk that diet and exercise could have fixed.
Like my pinned video says "We want to be small but God has created us to be great."
