I had a lucid dream breakthrough last night.

I was at a wake of a person that had died that I did not know. Also at the wake were people that I did not know, but there was a friend there that I have know for 15 years. In the dream I kept asking myself "Is this real?". I was pretty convinced in the dream that it was not. Then I asked my friend in the dream if it was real and she said "Yes, of course it is real". After that I believed that it was real.

Part of the reason I think that I was not able to realize in my dream that it was NOT real was that the dream of the wake was part of another dream that I was removed from. It felt like a dream that was layered, a deeper dream state.

My question is, how do you ignore the input of other dream characters that conspire to make you believe that the dream is real?
