WaterDreamer

My memory of how this began is kind of sketchy now:
I'm working on a class project with 2 other students. One of them, a girl, gets mad at me for some reason - unjustifiably as I recall. Since I can't stand to be on bad terms with someone IWL, naturally in my dream I seek out this girl later on to straighten things out.

The following I remember vividly:
I'm alone in a house at night. I'm possibly in that girl's house trying to find her. I walk past French double doors that are wide open; beyond them is a dimly lit back patio. There's a homeless-looking man sitting on a covered porch swing outside, and he's glaring at me. Part of his clothing is green, and he has a bushy beard. He looks threatening, he's not supposed to be there, and the doors are open - so now I'm scared. He's watching me, so as quickly as possible, I shut the right side of the double doors, and just as I try to shut the left side, he lunges at me. Holy crap!! I try to shout for help, but I find my throat severely congested and I can barely make a sound. He comes at me reaching with one arm, menacingly. Desperately, I reach out to grab his hand in an effort to stop him from grabbing me... and I wake up in bed, actually grabbing at thin air!

I've added this to my mental list of nightmares to revisit in future lucid dreams. Nothing against homeless people - heck, I give them money IWL - but I'll beat the living piss out of this particular DC the first chance I get. No one lunges at me from dark patios and gets away with it!
***** UPDATE *****
About a week after I dreamed this, a REAL homeless man who VERY CLOSELY RESEMBLED the nightmare DC came into my work IWL and acted very strangely. He had the same bushy gray beard, the same creepy look, and was even wearing green!! He asked about getting a job, hit on me, and started undoing his fly as if he planned to expose himself to an older woman who was getting fitted by our seamstress (I work at a drycleaners). I was about to tell him to get the fuck out, but he decided not to whip out his junk, and finally left.
