Nightmares

Since I started dialysis I've been having many more nightmares than before. I have always had vivid dreams almost every night (although I don't always recall them afterwards), but nowadays and especially the three nights a week after my dialysis I have these dark recurring dreams in which I'm always anguished or frustrated and bad things seem to happen to myself and everybody around me. Strangely I have yet to dream about dialysis itself, maybe my subconscious mind is still in denial!

Does anybody else get these nightmares? I really wonder why I get them because my thoughts during the day are never dark and I (almost) never feel depressed or afraid, though obviously I have some measure of apprehension when I think that I could be called upon for a transplant and opened up with a scalpel any day now...

They don't really bother me except that they sometimes affect the quality of my sleep.

Anyway, any thoughts are welcome...
