First lucid in years

Date: 12/27/2016

In my dream i was at some kind of festival. My grandma was there, but i then remembered it couldn't be real because my grandma has been dead for almost two years now. I did a reality check by looking at my hand to be sure i was dreaming. I had more than five fingers on one hand so i was sure that it was a dream. The dream continued for about a minute, but it then collapsed and i woke up.
