Hi, i'm new to the forum, but given that i don't usually dream but i have been dreaming a lot latelly so i want to try to find out what those dreams mean and why are they upsetting my sleep...

Reality part:
I was in a small bar with 2 friends of mine, and i spotted this girl (that i know from college but never really met her), our eyes met for a couple of times and one of my friends said that she couldn't keep her eyes off me, that same night i added her on facebook since we had mutual friends it was easy and when she accepted she said she liked my profile picture, i was attracted to her, and when she did that without even knowing me i thought that maybe she had also felt something as i have been told she is really shy and wouldn't do such a thing. I replied the gesture but didn't bring myself to talk to her yet. I asked a friend of mine if she had a boyfriend even though i never saw her with someone and there are no photos or comments that suggests that she does have a boyfriend, to my surprise her friend told that she has got a boyfriend, and i pretty much felt confused.
Since then i dream about this every single night with no exception:
I'm driving a car (i love to drive and race at local tracks so i can understand this) buy i'm not driving with my driving style and i can't do anything about the car, feels like it's a pre-programmed vessel, i can't steer, brake or accelerate, I'm just sitting in the drivers seat driving somewhere i don't know, not even the road ahead of me and i'm not driving any of my cars and i'm driving like i know the place which is very strange, and i come up to this house near my grandparents house the problem is this, i have no idea how but somehow i know i'm close to my grandparents house, and i don't know the house i'm driving to, i try to park the car in the driveway, and to my frustration i can't do it, i takes me forever but to no avail, then a door opens at the side of the house, i see 2 people that i know, my grandparents neighboors, they wave at me and the garage door opens, and i just park the car inside the garage with no problem at all, then this girl that i never saw in my life opens the car's door, and i get out and without hesitation, i kiss her, she took a step back and said to me:

Her: Don't do that...
Me: Why not?
Her: I'm having trouble with my boyfriend, it's like he doesn't look at me anymore.
Me: I'm having trouble with my girl aswell, i don't think she likes me the way she used to..

Then she kisses me, i hear someone calling my name from afar and then i wake up.
I don't know if reality and dream are related, but i know that i don't have a girlfriend, and in the dream i say i do and i don't feel like i'm lying or anything, just a sincere conversation.
I'm sorry for my english and the confused text. Thank you for reading/replying.

Edit: Just been reading a bit and i think it's what you call a lucid dream, because i'm fully aware that i'm dreaming but i can't do anything about it, feels like i'm in the "story" but just watching.

The part about driving the car could be about how you feel about this girl - you don't really know much about her and you don't have any control over how she is going to respond to you.

The conversation you have with her about troubles with your boyfriend/girlfriend could be your unconscious' way of saying that you want something to change.

Thanks for the reply Marcia, do you have any thoughts about the location of the dream?

Do you mean your grandparents house?

Grandparents could represent the past, security, wisdom, authority, etc. - depending on what your grandparents mean to you.
