I've also taken drugs that enforce that sensation and it's much more interesting and tolerable when you've done it intentionally, know what's happening, and that it will end. Those mind states have allowed me to explore emotions and sensations from a rather removed point of view and have some realizations (pun? Not intendes) that i wouldn't have otherwise.
If you wear glasses, chances are you've learned to ignore the constant frames around your vision. I'd like you to intentionally notice them. Do you see how the vision you experience could be likened to a movie screen? You can look around but you are trapped inside this frame. Imagine if you weren't wearing glasses but you came to notice the frame at the edge of your vision. And upon noticing, found yourself incapable of slipping back into your regular sight. Like you've been pushed back and out of yourself, and you have no way to get back in. You're still in control but it's just that, _control_. It's not you, it's just control, and you can't make it you, no matter what you do. That's at least what it's felt like for me.
Later I took a much smaller dose of salvia and I didn't hallucinate but still got the strong feeling of derealization. It's so hard to describe but everything seemed "fake" or "plastic". Like hollow and so lonely. Maybe, I guess, what looking at a scene through VR would look like. The sun didn't feel warm, the grass I was touching had no feeling of comfort with it (?). Ah, I thought I could describe it but it's so hard to describe, I give up.
If you take a small dose of salvia you can understand what it feels like. Definitely don't recommend but as far as I know, it's harmless and (for me) impermanent.
depersonalization is hell this time if feel like you arnt real , the effects of depersonalization includes the following . 1.Visual disturbances : everything feels like low fps and blurry . 2. Spatial disturbance : it feels like you are controlling your body like a robot 3. Physical sensation : touching your body feels weird as if it didn't feel like it used to , the sensations and even the size of your limps when you grab it feels different. Even looking at your self in the mirror feels like looking at another person
