I use the word "visions" in this thread though that's not exactly accurate. I am in my second trimester of pregnancy and under a great deal of stress, really a ridiculous amount of stress, and i am wondering if that is what is causing me to have very unpleasant intrusive thoughts at night. I often wake up around 2 am in a panic and can't fall back asleep until around 6 or 7, and the whole time I'm awake it's like my mind if just a hurricane of dark, terrible thoughts. Last night, for example, I started to worry about an upcoming flight i'd have to take for work. Suddenly I had these gruesome images in my mind of plane crash victims; it was insanely graphic and i felt like i was rummaging through the wreckage and bodies myself, but i couldn't block out the thought. And it was weird because the "visions" were intrusive, I didn't consciously lead myself to such thoughts. All i thought was, "oh, i'll have to fly." And suddenly I was bombarded with grisly images of death and I couldn't turn them off. What is this? Is this just severe anxiety? Has anyone else had this? I should also stress that these aren't dreams, i'm fully awake.
