what would you do if u r home alone and you saw some think that looks like u ?

Look like me? That would be something interesting for me. If I'm not mistaken, If you would see someone who looks like you when you are alone, that is called "doppler ganger". Based on what I know, that appears when you do talk to yourself always. Well, I don't really know if it is a fact or a fiction. I just have heard or read it maybe. Well, I wouldn't be afraid that much. I would be curious.

o that would be quite interesting... atleast i will find someone to talk to or share my emotions... to be alone is boring... so my own company... i don't mind really... but may be for the first few minutes or so i would be a bit scared... but not after that...

What would i do when i saw something that look like me? I would be sure that i was staring at my reflection on the mirror ;) Those "what if?"s will do nothing to you but make you worry so try not to think of such stuff. Find something to be busy with; watch tv, read a book. If silence gives you the creeps as well, turn on the radio listen to some music. If you are "sure" that you saw something moving, make loud noises and hope that thing to react to that. If not, maybe that is more scared than you are. If you are not brave enough to grab a knife and turn on the lights, then stay where you are and mind your own business, that "thing" won't be able to move because it will think you are well aware of its existence ;)
