I've had quite a few dreams like that, but I've always tried to be at least a little bit skeptical of myself because very rarely have the events in the dreams played out EXACTLY like the real life events they seemed to foretell, and I usually have to delve into the realm of symbology a bit too. For example, a few months before 2pac died, I had a dream where I was watching the news on a Sunday and found out another rapper, Bizzy Bone died. The only real similarities between the dream and the reality were the fact I saw it on the news on a Sunday, and considering I didn't have an internet connection at the time, even seeing it on the news isn't that significant because where else was I going to see it?
Another example I posted about quite a while ago had me dreaming I was getting in some kind of shit in residence for something I had nothing to do with and having the R.A talk a load of bullshit about how I have to take the blame even though there's no evidence against me whatsoever. The very next day in the real world the same R.A is blaming me for (get this) writing my own name all over a bunch of bathroom stalls. To add another connection to it I had to think back to another dream I had several months prior where I was walking around the campus and seeing this symbol of mine all over the place and having the feeling someone was trying to get me in shit. Since it's a symbol I created, I guess it COULD be construed as an identifier of sorts, but in the dream I had later, I wasn't explicitely being blamed for that. Not only that, but in the dream with the symbols, the bathrooms were about the only place I didn't go, so I didn't see them on any stalls. The truth is, at the time, I WAS genuinely paranoid about getting in trouble, but mostly just for having the wrong friends, not because I was vandalizing shit, and my mind could've been acting on that.
I also have to wonder sometimes if our minds, being a lot more fluidic and permeable than we sometimes like to admit don't have the ability to conveniently alter memories of dreams when real life situations appear to resemble certain parts of them.
