Well, you probably would have done better to eat the shrooms, rather than make a tea. Oh well, there can always be a next time, lol. Shroom trips are a great way to get used to psychedelics, since they aren't as harsh as other drugs.
DMT tends to cause powerful open and closed eye visuals, generally geometrically patterned, at mid doses. At high doses, like many other psychedelics, it can cause a breakdown of what is referred to as the Ego. This is tripping hardcore, in the most powerful sense of the word. The ego is what makes you You. The ego is your perception of yourself as a person, separate from other people, and the world around you. When you hit the point where you are beginning to lose your ego is when a lot of people really begin to become scared, even if they are somewhat experienced. It's a completely alien feeling, it's beyond visions and tripping in the conventional sense, because you are no longer separate from the trip, and from the things you feel and see. You are one with the trip, in a sense in that state, and the process of losing your ego can scare some people shitless. Of course, the other side to that is that this is the state where some people come to have religious experiences. You think in completely different ways, and come to understand the world from an entirely different perspective. Only the most powerful of trips will ever bring you close to really losing your ego.
DMT is hard to get (harder than most, even the obscure drugs), but it's not really recommended to anyone who doesn't have much experience with psychedelics anyway. It's a harsh drug to smoke, it's a harsh strong and alien trip, and it has the potential to bring you further past your ego than any other drug.
Another interesting psychedelic to try is LSA. LSA is the natural occurring substance that LSD is very similar to. The best way to experience LSA is through Morning Glory seeds. The main issue with that is that even though it's fairly easy to get a hold of those seeds, you need to eat quite a few (I've seen people talking about needing doses between 200-400 seeds), and you are pretty much guaranteed to get sick (I believe it's a natural reaction from the way your body deals with LSA). However, it does apparently have some very nice effects. It also lasts for a long time. (We're talking, 2 hours after getting sick, before you feel anything, IIRC).
