I LOVE music-inspired nightmares. (SPOILER)For me the usual nightmare means nothing to me. I usually fully take part in gruesome murder and mayhem in my dreams or just sit by apathetically like when I dreamt about people chopping off people's heads and keeping them in boiling pots of water/microwaves/ovens to "Keep them dead." For me, my only "nightmares" are the ones I have while napping during the day when I realize I'm asleep and constantly see myself where I last was when I started the nap and am constantly trying to wake up and each time I "wake up" it feels so real.
