Oh I sincerely doubt that you are having these dreams as a way for attention. When we are the center of our dream that seems rather normal, imo, especially when you are little, you don't know how to look through another's eyes then anyway...the whole world is all about you!
I can control many of my dreams (lucid dreaming) but that doesn't mean that the ones that relate to my accident aren't bad memories and the like. I do really well with flashbacks these days, as compared to the first 18 years

but they are still from the PTSD from the accident... you get what I'm saying?
I think questioning why is very normal also, and denying that they are connected is too, imo. What might also concern you is when you realize other dreams that you thought had no connection whatsoever, are also part and parcel of the traumas. It's ok, though... just another way your brain/mind is trying to file those memories away properly.
