Psychedelics
Ive always found both the reality altering hallucinations as well as the reality replacing ones, absolutely worth it every time. In fact i tend to think mushrooms are the best trips i ever had, of a fairly long list of other experiences mushrooms rank at the top.
While the morphing altered colors etc can be very fun, its the higher level doses of most of the psychedelics that are worth the experience and any fear they cause. I think its the higher level trips that you can learn more from, some of the best trips i ever had were high dose ketamine and salvia trips, replacing reality and being shot to the end of the universe, playing with the edge of reality like a piece of fabric.
I havent had the chance to try this with psilos yet but i have a feeling i will soon

If you can handle the anxiety they may cause, and you can handle the trip itself, which is not everyone for sure, then higher level doses of the "real" psychedelics can be far more rewarding than colors moving around etc.
The problem is not everyone can tell if they can handle it beforehand, numerous people (on BL) have contacted me after serious problems resulting from a trip, in some cases long term psychotic symptoms occured weeks afterward.
Notwithstanding the complications it can still be rewarding for a lot of people, perhaps its possible to tell how well you can handle a high dose trip by what happens on lower doses, perhaps not.
I would be interested to know how many people have felt a presence during a trip like this, either seen or unseen. I could definitely feel something there with me with both ketamine and salvia, both times it didnt seem angry just seemed...well.... sort of like a superior presence, toying with me sort of like hazing in college haha
I think since we have threads about all of the psychedelics and there effects, perhaps we need a real comprehensive thread about what people experience with these kinds of trips, what it could mean, what the common themes are, and such.
