I had a dream the other night, I saw myself in the mirror and I had my old hair style. But the thing is I knew it wasn't right, not straight away but after. I used to gel my hair up but now just have a shaven head and anyway in the dream I was geling it, then a small time later I went back and tried to rub it all out, thinking "That's not right, I don't do that anymore" and then the strange thing is I looked at the back half of my hair and it was my current style (shaved)....

My question is, I KINDA did recognize it was wrong, but I didn't realize I was dreaming or become lucid. Why is that? Am I close by just realizing it was wrong? How can I improve my dream signs or so that I recognize them better? I've been doing reality checks throughout the day but have yet to do one in a dream.
