Dream of

I'm in an old factory/nursing home place a guy says here hold this for me and as I walk away I realize its an ax. I turn around and he has a huge knife that he's killing someone with. My childhood friend is soon next to me and we begin to run to hide soon he finds us and kills anyone in his way to get to us. H never gets us cuz I wake up scared before he gets that close. Then I can't fall back a sleep. What does this mean?
