I think you missed the point what I meant slightly, and that's ok, my fault. I'll try to clarify.

There is a meditation similar to the effects of a dis-associative in which the practitioner simply recites a mantra, "I am not that", to each feeling, sensation or thought that arises. The reason being, say you have a thought about how much you want to help a stray dog, normally we'd just assume it was us having the thought, but if you are in this meditation and pay attention, you can't be that thought because what is really "you" is what is merely observing that thought come into your mind. There is a degree of separation that gets missed when we identify as our thoughts, feelings, desires especially, and definitely emotions too.

I think compatibilists deny that this degree of separation exists from a strong habit and/or intuition of identifying themselves with these things.

With your second bullet point, that was not at all the intention of my proposition. It's not about the sense of self becoming cloudy and doped up. If you were to take one of these drugs, not that I recommend it, but at the right dosage, you would find that the "drugged-self" as you put it, is not cloudy or deluded, it is still fully intact and aware, it's just the bonds between that self and the things you listed, emotions, desires, etc, are weakened to a degree that the drugged-self realizes, that is in fact, not, who I am.
