reminds me a little of an experiance i had, i think it was OBE or it was a very vivid dream.cant remember now how the beginning of the dream went but i ended starring at my self in the mirror and it looking like a portal,so i jumped in it,within the instance i was floating above my body in bed,watching me and my girlfriend sleeping,woke up straight away and we were both in the exact same postion i had just seen.
not really like your dream at all really but involed my reflection.
when i come more experianced with lucid dreaming and can control my thoughts in a dream and not get to freaked out,i may try and meet my self.
