Yeah, I had several soon after I was diagnosed with a serious life threating illness that REALLY freaked me out.
In one I was flailing around in the wake behind a ship, I guess I had fallen overboard but I don't remember that part. It looked just like the Titanic. All of my family and friends were standing on the fan tail as the ship was steaming away and I was screaming begging one of them to please throw me a life preserver because I was drowning...but they all just waved. I think it was because I was symbolic because I thought I was going to die and they were going to go on living.
I had two others where I was visited by dead people. One was this neighbor who had been almost like a second father to me when I was growing up. He had recently passed away at age 76 due to diabeties. He appears in my dream and tells me that I am going to die, but that it was nothign to be afraid of and that he and I will be hunting and fishing together again soon. (when I was a kid he used to take me hunting and fishing with him all the time) Since I had been close to him this one didn't freak me out as much as the second one.
The second dead person who showed up in a dream was this kid half brother of one of my high school friends. I had only met him once when back when he was a teen and was in a boat with several other friends of mine who stopped by my boat dock one weekend. That was the only time I had ever met the kid. Anyway, years later I heard that the he had been killed when a piece of machinery he was operating flipped over and crushed him. So anyway he shows up in my dream and tells me that I am gonna die, and that I am way too worried about it and that "I just really need to chill". because dying is nothign to be scared of. At first I wasn't sure who he was then I realized it was Brad, my friend's kid brother who had recently been killed. It sorta freaked me out because I never even knew him when he was alive but I remember thinking he was really cute that one time I met him.
I usuallly don't remember dreams but when i do they are always in color...just like I was really there.
