Can't sleep again

I was half asleep in my bedroom, sorta listening to some show or video my wife was watching in the living room. I had almost drifted off, when I heard a metallic clang. And then ... I was someplace dark and cramped. I sorta knew I wasn't actually there, but it still felt real. I think I'm mostly grounded again, but I'm still smelling paint every once in a while, and my heart starts racing. Got all the lights on, which is helping a bit. Still a bundle of nerves. Not sure if I'm gonna be sleeping any more tonight.
