Why does everything not feel real.

I have no idea what's going on with me right now.

Nothing feels real at all.

Spent some time at my grandparents tonight and it just didn't feel real. Like I wasn't actually sat there having the conversation. Trying to explain I'm okay but really I have no idea what is real anymore.

It's so frustrating, and it's making me recluse myself even further from the outside world because I don't know what I am supposed to believe or tell if the things that are happening are real or not.

Why does everything seem to be so much brighter, like there is no glumness to the world. Like walking down the street and thinking I'm not really doing this, it's just a dream.

Feels like I'm in a complete dream state all the time.

During extreme depression (bipolar) or when I have a extreme feeling of embarrassment from a failure (triggered by my NPD) I feel very similar to what you describe. It has gotten bad enough that I seriously question if objects and people around me are real or just illusions.

From me I believe am fleeing something that is too painful to absorb straight on.
So I work on improving the parts of the situation I can and accepting the parts I am stuck with. Not an instant fix but the feeling I am real again returns in time.

A Therapist that you click with well could be helpful in helping you feel grounded.

I think its possible to get depersonalization even without any psychological pain in the background but I do not understand it. If that the case find a specialist who can help you figure it out.

been there man. i thought i was in a dream so hard i smashed my car into another one and drove away cuz,,, its a dream right? no consequences? but when i got arrested and put in the psych ward i started to slowly realize that although, yes, this time here on earth is a very perplexing thing, i do not have it all figured out. and neither do you. i dont know what is causing you to be in this dream state but whatever it is youll probably learn a lot from it and when you come out of it (which you will) youll have a better understanding of reality and the ones you can create. just dont hurt yourself or any others in this state. its weird right now im sure and if you wanna talk more about it pm me. id love to share my story and hear yours
