Can't get people I see in dreams out of my head.?

About 2 weeks ago I had a dream where I saw a woman and her baby and they had died. The night afterward I could not get the woman's face out of my head. I have no idea who they are all I know is that I could give a perfect description of this woman's face for the next 3 days. Last night I had a dream and in this case they didn't die, but I can give a perfect description about what she's wearing, how tall, and what her face looks like. Also this time it's someone that I've seen before. I still don't actually know her but I've seen her either on tv or at a store or something like that. I want to know if this is just me having a stress buildup come loose or if I am actually seeing people that exist.

Just a note I have had dreams before that come true for the most part (colors or distances were off by a bit, but the jist was there).
