All of these have happened to me too O.o I was freaked out when i first found out i could do it. I can remember it clearly. Its not just in my room. I went over my friends house for the first time and we were playing hide and seek in the dark (haha, we are idiots XD) and i knew my whole way around. I even knew where all the picture's and ornaments were, even though i had never been in half of the rooms. Haha! I have kept this quiet because i thought people would think i'm crazy! :D Who knows? Maybe i am? Tee hee!! ^^

I understand how you're freaked out, but you'll become accoustomed to it. Most likely, you have ESP. And NO it's not fantasy, it's real. ESP is when you... Well look it up 'cuz it's hard to explain. But it's like you can sense the aura of the setting you are in or somthing or other. In fact, some of it happens to me! Pretty cool though, huh? ESP is stronger in some people who have it more than others. You seem to have it pretty strong, mine must be weaker, though. But don't worry, if you DO have ESP, thr military won't put you in Area 51. Hope this will help you calm down  a bit!

Haha, freaky. But I guess it happens to all of us some time in our lives. XD The scariest I think is when you predict what people are going to say next. o.0
