You encountered hostile aliens, in that trip. I’ve met lots of them. What they do is pin blame upon people, even blame of events where the person wasn’t even alive at the time… ie: the Second World War. Those beings are simply bullies. They are not trying to teach you anything. They are trying to frighten you. I have many such encounters, and believe it or not, even worse encounters. This planet is an industrial grow-op, and it is controlled by hostile entities. God exists. You should seek the protection from higher powers. The hostile aliens can sequence thought forms that can make believe anything… well at least in your naive state. Don’t believe anything you are told from unknown sources. And, a big part of your discomfort was with the toxic effects of the drug. If you hadn’t felt physical sick, you would have faired much better
