^Yip I agree, I thought this too.
The second time I did salvia was on a bicycle track with a group of smoking friends. I took the hit and everything went weird, with everybody there standing watching me to see what happened. Then one of them sort of raised their hand in the air with a big smile on their face and said my name, then as they did so raised the other hand and another continued the process and started doing it himself. Then they all started raising it one after the other and repeating it. I thought they were just trying to freak me out, so I accused them and they denied it. It was so ritualistic and perfectly choreographed, and it was only a few years ago that I realised that this probably didn't happen.
I've definitely had the feelings of anger though, and I've witnessed it. I can remember gently placing my hand on my ex-girlfriend to ask if she was okay, but she got very angry with me and shouted at me, telling me to get off her. I completely understood because I've done this myself; experiencing an intense feeling of irritation at normal behaviour.
An interesting example was in my friends living room. There was something in the corner, which I can't remember, but basically it was a breach in reality towards salvia space. If you've smoked salvia, you know what I mean. I looked amazed and my friend asked what was there. Suddenly I just snapped at him "No, you can't have it" in a very angry voice fuelled by a degree of keeping whatever it was to myself that was Gollum-esque in tone and nature. I kept repeating "No, you're not allowed, you can't have it", which just made my friend ask me more, then I sort of snapped out of it and couldn't remember what it was. I literally sounded like Gollum talking about the ring in LOTR.
For the record I am very laid back and calm. It's just not like me to get angry (unless you're actually being a cunt), at all. I feel like the irrigation and anger is usually accompanied by the prickly, uncomfortable, pins and needles side of that world.
