Is it normal to dream about your girlfriend then waking up expecting her there?

The first dream i had of my girlfriend is when we were cuddling, it felt so real, then i woke up and said "Hannah?" (Not my real gf name) because i thought she was actually with me, of course i felt a little upset seeing that she wasn't there.

The second one was when i was speaking to her in my dream, then i woke up too look at the time then i thought "it's a bit late for her to be round" so i turned on my flash light to see if she was there, she wasn't. So i got out of bed to put my shorts on, then i asked my self, "if she here or was it just a dream" of course it was a dream, then i went back to bed a little upset that she wasn't with me.
