I feel like if I was dreaming constantly throughout my life.

I know your feel. It's called depersonalization disorder, but I prefer to call it derealization, both are used interchangeably by psychologists. I used to have it really bad and had extreme waves of it where everything felt weird and fake, like something about the very nature of reality was false, even my eyesight and depth perception got really bad during these. But it went away a bit and only feel it slightly.

I wonder if that's because of me staying in my room for most part of my life

I have it too, although it could be plain old depression in my case.

But basically it's as if life has lost its soul, as if the abstract emotional reality created by my mind has been lost and all that remains is the physical, logical reality.

I know how you feel, kinda. For me it's like i'm living a fake reality, but it happens only when i'm with other people, at work for example. I don't know, it probably has to do with me changing my personality based on the ones i'm talking to (i don't want other people to think i'm a loser, i don't wanna be bullied again). I also noticed that i can predict situations more often. Also deja vu's

this,
like feeling detatched from life, unplugged at some point in my life and now it's just white noise
