I have just started...but I don't think it's going to traumatize you. For example some people have spiritual conversations with themselves. This changes them, because they learn about themselves and the world. It's like having a teacher/mentor who makes you see things different. It changes you I ho...

That's kind of what I am afraid of... Do they mean that the sound waves will fry your brain, o that your personality may be too weak and may change after the views? O do they mean that you'll get addicted?

Hi, almost every hallucinogenic i-dose says something like "WARNING: It's a life changing experience".... I mean are these effects life-long?

Well, if the room is pitch-dark then it doesn't matter wether your eyes are open or closed (during hallucinations, cause in the beginning blinking may distract you).
