Welcome!

Honestly, I would be skeptical as well. We often dream about things that hit close to home. I, for example, always dream about friends and the environments I'm in.

It's not uncommon for our greater fears to be planted in dreaming, as dreams are often about what happened recently and/or deeper feelings. (in essence it is keeping the pathways in the brain active.) I've had dreams where horrible things happen to those I love, more often then you might think.

You mentioned just how close this person is, leading me to believe this was a dream depicting your fear. Also you mentioned having nightmarish dreams early on, making this even more likely. Unfortunately something did happen in real life that corresponded with it. Do I think it was precognition? No, my humble opinion is coincidence.

I'd love to talk to you more about it. Feel free to respond.
