has anybody done this before?

Just recently i had experienced something like it. One dream i was a superheroish person fighting and flying and the other dream was me talking to wasup on online. At first the superhero dream happened first but then later on it transitioned into 2 different dreams. The best i can explain how this worked is comparing it to firefox and its tabs. Imagine that there are two tabs each with something different on it. if you click one or the other is brings you to a whole other page. This is how i did it. I just "accessed" the other dream and when i wanted to go back i just opened up the other one. I probably wont be able to do something like this ever again since its sorta complicated for me to do willingly and probably to much concentrating.

strange part was Im not sure at all if i was lucid dreaming. I know i hadn't expressed it verbally but i might've known deep down somewhere. During my conversation with wasup i had asked him if he had every dreamt 2 dreams at once and i told him that i was doing it right now. maybe it was a semi lucid one...meh..

well just felt like sharimg my experience. questions, comments are welcome
