Paralisis symptoms and conditions

I have never experienced anything like this before starting Zoloft. Most nights, I have very vivid and disturbing dreams. The last two mornings I was having really vivid dreams, almost nightmares. These dreams were NOT fun! I eventually became aware I was dreaming and I forced myself to wake up. When I woke, my body was in a near state of complete paralysis. I could move very little and had to stay in bed for about 30 min. before I had enough energy to get out of bed.
