Dreams about death...?

Hi, all...I have a couple of dreams that are slightly disturbing to me. I know dreams aren't to be taken literally and that death dreams are not necessarily bad, but the fact that I've had similar dreams about two people in the same family (a mother and son) make me wonder...

The first dream was about a man I used to date and still keep in contact with on occasion. In short, he and I were somewhere together and he ended up getting killed...I didn't actually see him get killed; it was almost as if the dream "skipped" or "fast-forwarded" to me only finding out what had happened after the fact; I was standing in a doorway and they (I don't know who "they" were) were walking out of the door carrying a coffin, and when I opened the coffin I found him inside.

About a week or two later, I dreamed about his mother; I was at my ex's sister's house getting ready for his wedding (he is actually already married and has been for about a year now), and we got a phone call that said his mother had been killed in a car accident that took place when she was on her way to the wedding.

I wish I had more details but that's pretty much all I can remember. Any help with this would be appreciated. Thank you.
