What would it mean when I had this weird dream about my girlfriend just last night ?

[Marcus]

I don't why but I had the weirdest dream ever last night when i was sleeping. I'm an 20 year old guy and I'm currently living with my beautiful Asian girlfriend and I love my girlfriend a lot. She is my like a thing that keeps me alive and I would die If I didn't have her. She and I been together for 2 years. She and I are about the same height and she is really cute, especially when she puts on a pair of skinny jeans with some stiletto pumps shoes, I never knew what those shoes were called until I lived with her these past 2 years. But I had an very weird dream or more of a nightmare last night, I dreamed that she and I were out in town and when all of a sudden some sort of thing made her vanish into thin air and next thing she came to me dressed in a white robe dress wearing clear heels and kissed me and then walked into the sky. Then I was searching everywhere for her and crying out her name, next thing I knew I woke up from my sleep panting and sweating and crying. I was in bed with her and she then asked me what was wrong and I said nothing and she then looked at me and went back to sleep. So what did this weird dream meant ?? Did it mean that something bad is going to happen to her ?? What should I do ?? I feel so scared for my girlfriend and I love her so much.
