Randomly Honking/Headlights Flashing

Ok, suddenly my cougar has started randomly honking and the headlights flash every time that it honks. I'm assuming it's something to do with the alarm system, maybe a fuse or cable or whatever, but how do I fix the problem. It will stop for like 10 seconds, then start randomly honking fast then slow, then it will stop for like a minute then start again for 5 seconds. Is it possessed or what? Lol. Please help!
