ELI5:If there was a way to remove a brain from the body and keep it alive, what would it feel?

Had a recurring nightmare where my brain is removed and experimented on, I get these hot, agonising pains. Thought I'd ask what would actually happen if the brain was kept outside the body (if we know).

An easy metaphor for it is to ask what a person that's had a traumatic spinal cord injury and is paralyzed from the neck down feels.

Nothing.

Now add in what a blind person sees and what a deaf person hears: blackness, and nothing again. 

And then just strip out the other senses because the brain's not plugged into anything. 

So, blackness and nothing.

I'd imagine insanity wouldn't take very long at all to kick in.
