Inner fantasy and delusion?

Do you guys ever have a strong imagination? Or an inner world?

I’ve kinda been living in a fantasy world (still know what’s real and what’s not) for the past week or so. I get so immersed the real world feels wrong… like the real world doesn’t feel real, like I’m in the wrong place. That inner fantasy becomes so strong it’s like my real world. Idk maybe it’s a very weird strong disassociation or derealization. I just recently fell back into the real world again, and everything seems strange and loud. Not real.

I still understand what is real and what isn’t, my inner fantasy is so strong that I rather be in that world than this one. I remember this is how one of my worst psychotic episodes started. I’m not sure if this is the beginnings of an another delusion or just something weird. Like the real world has become so alien to me I really want to escape from it. I’d father live in my fantasy world than this one even if it means living in nether world at all. Like I just don’t wanna be in this reality at all.

Has anyone else felt this way?
