Dmt, Has anyone ever used this powerful drug? Options

I guess Shamanism is the best place for this.

I've been thinking about "entheogens" recently, mainly mushrooms and DMT
I have some DMT I've been saving for quite a while. I was going to smoke it within the next month with a couple friends, I never have before. I've only eaten mushrooms about a dozen times and did LSD once.

I was just wondering if anyone has taken DMT before, and what kind of information may be found when under its influence.
Apparently some people are under the impression that any time you take any entheogen you will be given divine metaphysical information.
This is of course absurd. I've never gotten any information on my trips.
Perhaps when taking the drug you should have the strong intention of learning?

IDK, any insight would be appreciated

I've smoked salvia a few times with odd results, I didn't like the feeling very much but I'd like to try it again. Each time I've smoked it it's been my friends homemade extract.
I remember the last time I smoked it, I felt like someone was trying to push me down with their hand on my chest (I was sitting cross legged) I kept leaning back then resisting and sitting up straight, that went on back and forth for a little while then it just kind of faded away.

I also tried a little datura once. I was feeling a little strange, kind of like the start of mushrooms. Then 45 minutes in there was a moment where I felt like literally anything could have happened. For less than a minute I was wondering what would happen next, because anything was possible. Then when I started to get frightened at the possibility of some type of demonic beast appearing and attacking me, I instantly came back down and felt more sober than before. I probably wouldn't try that again unless I was with someone who has a lot of experience with it.
