What does it mean to dream that you start to like a girl?

It means it’s not worth bothering about. If it happens a lot… well then you have my sympathy.

You’ve literally just discovered the girl of your dreams!

I think there are many “potentials” out there. Your dreams are letting you know that.

She is a real girl that you’ve seen or just one in your imagination?
Reading between the lines is the best way to interpret dreams.
You want to meet a girl like the one in your dream and have her as a girlfriend.

See if you can remember someone from your past life..) On a serious note she might be someone you would like to meet / think as your perfect partner with those characteristics.

How the dream made you feel is more pertinent than its imagery or “symbolism.” Happy? Sad? Hopeful? Wistful? Think about that and then try to connect that emotion with a past, present or future event.

Maybe you are picking up that she is thinking about you?

It could be a succubus. Or some other dream spirit. Or something else. If it were my dream, I’d think it had something to do with my interest in a romantic relationship, and try to read it with my feelings rather than analyzing the symbols.

Nothing at all, forget about it and move on with life among the conscious.

You are either hitting puberty and expect these dreams nightly or you are a 40 year old virgin and your parents are threatening to kick you out of their basement if you do not find a job and move out soon.

It just means you’re frustrated and your mind is entertaining you, the best it can.
