One of of these shock inducing dreams I did wake up in pain still lingering, but there were no physical injury. I resisted a ghostly entity just a little too much. She was very scary, but I stood strong reminding myself my waking body was very safe. The ghostly girl kept warning me to stop resisting and to give into fear. The two of us were in sort of a power struggle within the dream. Then she lets out a blood curdling scream with the whole dreamscape pulsing. I get giant lumps all over my body and dark spider-like creatures started rupturing out. I was in so much pain and was bleeding heavily. I actually thought I was going to die. I woke up from it still feeling the pain and went into shock. Perhaps my brain was misfiring signals? I had to be taken to the hospital. There were no physical injuries like in the dream though. I had dull pain allover for for a week following that, doctors were puzzled. This is one of the reasons I don't try to manipulate the dream when I'm lucid nowadays. Q^Q
I'm so grateful I get nightmares rarely.
