Jun in my nightmares...?

I had a dream last night.. which I actually sort of remember. It's been quite a while since I woke up (about 5:30pm right now) so.. of course I don't really remember much but it was a scary enough dream to keep me awake for about another half hour.

Yes, it was a nightmare. (if you didn't assume from the title).

Now, I'm not sure if the main person in my dream was Jun but something in my head tells me it was and I remember the first thought in my head after waking up was "I am never watching Jun if he is in a horror movie...". In fact I've basically convinced myself that it WAS Jun in my nightmare but if it was.. that's not a good thing. Jun is.. well he's my ichiban in Arashi, so I cannot for the life of me understand WHY he was the scariest person I've ever met in a nightmare.

I don't remember much but here is the gist of the dream from what I can remember.

Basically.. Jun is walking around and he pretends to "save" people who are in trouble from falling off cliffs with rope, but that's what it SEEMS like he's doing. In actuality, what he does is he grabs those people's legs and snaps them apart with rope, and then.. those people die, but then they suddenly appear as zombies and do the same thing Jun is doing. For some reason Jun is NOT a zombie but he does this for some unknown reason that I am not sure off.

And just to let you know.. my dream was INCREDIBLY gory, like.. think of Saw I/II/III/IV - Yeah, that gory. Honestly I was terrified the entire dream. Like I could literally feel my heart beating like crazy even though I was only watching the dream from third person and wasn't actually in it myself. Honestly the dream might make a good movie or something but... seriously why was JUN the bad guy? And when I woke up, I was actually trembling. 

I can sort of remember the image of him. He has his 2004, Iza Now! concert hair with his blue suit from earlier episodes of D no Arashi and basically he's looking all rich, bad-ass and evil. But again I'm not entirely sure if it was Jun.

I'm sort of sad.. I've been wishing for an Arashi dream and the first one I get with Jun is one that scares me to no end and has Jun seem like a physchotic killer.

I wonder.. is there something wrong with me.. like.. mentally? o_o
