I have had a few. I had a dream that was similar to 9/11 2 months before it happened, and one day at work I felt weird, like something was wrong, my dad came to my mind so I called my parents and there was no answer. I was at work that day and I kept calling because I felt like something was wrong. Something told me to call the hospital and sure enough he was there. My stepmom answered the phone in his room and said....."How did you know?" Would like to hear other experiences.
