I woke up recently next to a friend and he was literally shaking all over. It scared the life out of me. I thought I'd have to call 911. I thought he was having a seizure or something. Then I leaned over and put my arm around him to see if it was just a nightmare. It calmed him down and woke him up. I asked were you dreaming? But he said no and turned off to me. He just said go back to sleep. I think he was having a nightmare. Has anyone else ever noticed a spouse or friend having a nightmare that caused their whole body to shake? Can that happen?

I've read that you shouldn't wake someone having a nightmare but I just couldn't help myself. Do you think it's a bad idea to wake someone?

Thanks for any thoughts on this.
