What does it mean when you dream about home, but the home you dream about is a house you haven't lived in for ten years?

In keeping with earlier crack-headed dreams; I had a dream last night. It was odd in the way anyone blowing their head off is odd. I was at home and there was this strange guy there. Mid 50's stocky and bald, I don't know this person. I don't know why he was in my head last night. I surely don't know why my head decided it was prudent for him to remove his.

I think he was an associate of my Dads, former army pal or something. At least that was the premise, as I have met some of my dad's army buddy's and this guy looked nothing like any of them. I'd venture to say he was very Danny DaVito-ish; only bald and more tan. Anyhow this guys presence was not of question to my parents so he certainly must have belonged.

Anyhow he didn't show up for dinner and I was sent in search of him seeing as he was lodged in my childhood bedroom. When I got there, I saw the red splatter on the walls and turned around. I felt nauseous, because of the blood to be sure. Anyhow I told my parents they needed to call 9-1-1, and then I rethought it. Considering the event was no longer an emergency, the guy was obviously dead, his head was on my wall, I told my sister she had better just call the police instead. No need in tying things up for a real emergency I guess.

Jump forward to staying in a hotel room, because well
