Hi.. Can you help me with my problem?

I have Noctiphobia & Necrophobia.. Means I'm scared of night & dead stuff.. Cause every nightfall.. I keep thinking that zombies will come to my house.. And tear me to pieces.. or ghost's disturbing my house.. like poltergeist.. I know this may sound stupid but.. I've been watching Lost Tapes lately.. and.. it freaked me out on that zombie episode.. And I don't get it.. when I was younger.. I loved zombie so much.. because I watched the movie Fido.. now.. I'm scared to even look at one.. Before I got scared of zombies.. I bumped my head while watching La Horde.. A french zombie movie.. It was scary.. Then the dreams happened.. Now, EVERY NIGHT I keep something blunt next to my bed.. Please guys.. I'm 13.. And I'm scared of nights & zombies..
