false awakening

I had a false awakening about an hour ago, I was next to my girlfriend and thought I heard her talking to me and I was trying to tell her to wake me up, but she said I was just laying there mumbling in my sleep and then jerked awake. lol.
I had a few dream fragments though over the last day or 2. One with with an x, won't go into details , and the other was with an old friend. I seem to feel things in dreams that I can never feel in real life, I feel this kind of peace with my environment. Another one was I was in a huge downtown building like the one in Inception, and I was walking with my girlfriend. The one after that I was swimming in this cold water (I had the window open), and I was trying to navigate around an old ghost ship. I picked a huge tarantula from the water, and realized it might still be alive so I squished it in my hand, and then woke up.
I have a lot of short dreams at my girlfriends, I can never stay asleep there, i've had 2 false awakenings in the last 2 days there.
