Is it normal that i get urges to eat people??

Sometimes I get these weird cravings... You know how when you're craving something and you see it in your head as something extremely delicious? Yeah, like that. I'll be off in my own world, thinking about stuff, but then I'll get hungry, and my own "little world" will turn into a really dark place. If I'm hungry, it's just weird. I feel the need to eat something meaty whenever I have these moments, and sometimes it's, yes, human flesh. It's not like I want to practice cannibalism or anything, I really don't, I'm just unnaturally curious. Last year I accidentally tasted my friend's blood. It was salty and left a sting on my tongue, and recently, I've been craving it. Badly. The other day I pricked my finger on a needle and sucked the blood from it, and it was an unnatural combination of sweet and salty, and I loved it. I kept licking my lips, wanting more, craving more. Now my cravings involve me running up to the victim, biting into their shoulder, and ripping off a piece of human skin, all fleshy and tasty, followed by a juicy squirt of blood that I'll savagely lick up, accompanied by a big chunk of human shoulder meat. Sometimes I visualise it as me biting into their leg instead of their shoulder. But I don't want to be a cannibal? And I don't want to eat raw meat. As I'm writing this I feel the need to bite into something meaty. I don't know what to do. I think I've been watching far too much gore for my own good. I just want to know what it tastes like...
