It does make sense. Everything about that place was suffocating. Of course thinking of it would bring on the same emotions. It's awful that you're still plagued with these nightmares. I didn't really have any dreams while trapped, though it was still unsettling. I lost time. One moment I would be awake, aware that I was in the crypt with you and Jenny, and then next I would just... Slip into blackness, I guess. It's only now that I'm in my own bed that I have the nightmares.
I've done some looking into things, though. I've heard that it might help to think of a more peaceful or happy time. The trouble I have with that, though, is that it's difficult to push certain thoughts out of my mind.
