I been having this weird dream idk what it means?

Ever since I was little I been having this dream that I would be sitting in a restraint and start to hear this rumble in the background then it would keep getting louder and louder until it was so bad the restraint would start to shake. Then the roof would be ripped off by a giant and the giant would then pick me up by the shirt and sling me and I would wake up right before I would hit the ground.
