I didn't read every single post before posting this, so forgive me if anyone said the stuff that I said before.
Anyway yes, smoking can add a VERY obvious element over a psychedelic trip. Some people tend to like it a lot. I can sometimes get a lot out of it, but other times, it seems to "muddle" my trip furthermore and add a sense of anxiety on. :[ I don't like it when that happens. Often, I like to just feel the "pure psychedelia" without anything else added on. It's usually a lot more euphoric and less unsettling.
I think your worst mistake was that you were trying to hang on to reality too desperately. If you're going to have a trip where reality will be dissipating, you need to be in a better location for it first off, with people who will understand. "set and setting" lolz
You need to feel entirely comfortable with things and be able to let go. Fighting against the trip will make it wayyyy more difficult.
Let yourself be swallowed whole... Or if you don't like that sort of thing, then do lower doses.
Oh and another thing, just as a note, I would never be able to watch a movie on a psych. XD Maybe it's just 'cause I have "ADHD", but I just can't imagine that EVER working... I'd either get too restless and need to see things around me, or I'd disappear into my own world.
