I have horrible nightmares, usually about something bad happening to my children, or sometimes I have a new baby and something horrible happens to it. I mean really, really horrible dreams.
When my children were younger I used to have the recurring dream about forgetting them in a mall, or at a grocery store.
I dream often, a couple of times each night, and they usually aren't so great. the Dr. tried putting me on meds to calm them down so I wouldn't wake up so afraid all the time (it was interfering with my sleep). The meds never did work though.
I also have dreams about dying. This last time I was in a plane and we were at a very high altitude and froze to death, I always have the sensation of leaving my body and watching everyone cry. I've died so many times in my dreams I couldn't even begin to count them.
On the same note, my son and daughter have both recently had dreams about me dying. The same night. I woke up to them crying that morning and telling me I was going to die. If that doesn't freak someone out I don't know what does
