false awakening

I can only remember fragments from last night but I can remember a few parts that were vivid.
My friends and I were at some amusement park and were on a ride that you are elevated upwards in a cage and then dropped until you slow down at the end. However one my buddies was riding on the outside of the cage for some reason. We went on the ride again after he survived however we were with our parents this time as well. He decided to ride the outside but lost his grip and was killed on the way down it was bizarre and terrible at the same time.
After this dream I proceeded to have a false awakening at my home 200 kilometers away (im in Uni right now staying there) which I can barely remember and I awoke thinking that 'it was just a dream'. I then started speaking to my family about the dream I just had right after a false awakening I can't remember their replies and that was all I can recall.
