What does this dream mean?

Ok so I have this dream every once in a while that this huge ginormormous ship or demon thing is departing to like cause an apocalypse, and like brutally kill me. But when I wake up everything was like a blur... I am still unsure of what was happening but that's what it felt like in the dream. And lol you probably think I'm totally crazy now. But I'm actually pretty normal.. :) sooo yeah I just don't get that dream.
