recognizing dream signs

I just realized a few minutes ago that I had a lucid dream last night! Wasn't anything special... I was in a room talking to my parents, and my grandfather (who died last year). He had no face! So it was so obvious it was a dream, but I woke up... I have a lot of dreams about him though (my grandfather) so I think it will help me with LD's in the future, and being able to recognize that I'm dreaming, since I know he's not around anymore. I'm excited to be able to speak with him again, my dreams are the only place I can do that now. Anyway, just thought that was cool, I think I'll be there soon :)
