Hi Mario you might have been sleep walking and dreaming at the same time, these things do happen.
Dreams are giving us bits of information that we can work with in our current situation, a lot of the time we are digesting our day combined with for instance fears and emotions that we've not yet walked through/worked on. Since this is a dream of years ago it's not easy to see what it meant in that specific period in your life. You have to walk your time lines back in order to see what it was all about.
So the question is what do you want to establish with this old dream or why are you sharing your dream here. Do you need assistance with understanding the dream/dream elements or is there another specific reason why you shared this dream?
is a lot of information about dreaming on the Desteni Wiki.
