Do these dreams i have make me bi, or lesbien?

ok, im 16, and im female, and i have these dreams, like every night, that megan fox is my gf, and, it just us, and idk, we like make out and stuff, go on date, go 2 the movies, do normal couple stuff, and um, we uh, have , and all that... does this mean im gay, or ? i mean iv dated guys before, im talking to a guy right now i like, and i told about these dreams, but he dont take me seriously, he just says thats hot, and then goes on to things we should do with a chick. i dont know what to make of all this, what do these dreams mean? i mean i can picture myself dating a chick, but with a chick, like in REAL life, in the moment and stuff, and saying i love you and all that, i just cant picture myself doing. i think id be uncomfortble looking another female in the eyes and saying i love you. or having with another female, i cant picture myself ACTUALLY doing. (except in my dreams) idk. which brings me back to "why am i have these dreams nightly?" i thought about talking to my mom about it, but me and my mom dont have these kind of conversations, i would be embarressed to tell her that iv had thoughts of with other females. im not sure if im making any sense or not, im just trying to figure out what the hell these dreams mean..
