Is this your subconscious basically telling you that you are extremely attracted to a woman you once saw (but have since forgotten over the years) who so happened to wear a gray outfit on the day you saw her? Fascinating, if that's the truth.
I'll tell you the most insane, depraved, awful dream I ever had. In it, I killed my own older brother. Out of rage for a temporary thing of him annoying me, and I shoved his ladder off the edge of my bedroom window and watched him drop. No joke. It was so wrong and horrifying that I immediately had to take a shower when I woke up. I still don't know how to interpret it. Him and I haven't always got along, but Jesus, we're not just family, we're the closest of friends. I'd fight and die for him and he would do the same for me if it came down to that. So why this totally f-ed up dream?
Ignore all that if you don't want to speculate...I'm merely offering rhetorical stuff and getting things off my chest...you don't know me...I don't know you...and it's obviously impossible for you to truly interpret something like that from someone you don't know personally.
