I'm not sure if I have OSDD or any similar dissociative disorders, but I've experienced similar to what you've brought up here where I find certain thoughts are fairly alien to me, and in some cases I will taste or enjoy certain things that I would normally despise while eating. For example: I can't stand the taste of peppers/hot sauces and don't tolerate spice very well, but sometimes I'll eat things like buffalo chicken and not mind it at all. aside from that, most of my emotions and thoughts have always felt hazy/meshed together and are even contradictory to things I agree with normally.
