Maybe both. I do think it depends on the person though if they're more the type to want to talk about it or more the type to keep it all in.
I wish I had a solid answer for you. I've seen people mention pets from the dreams showing up, and there were weird birds for a couple of days. So the possibility is probably there? I just don't know if there has to be a very specific connection for things to show up or not. Sorry.
