Active in attic & then throughout

Earlier tonight I was outside and checked the attic window to see if light was on, as I always do,it wasn't. About 10 minutes or so  I went back outside & once again checked the window & the attic light was on. I came back in, got karen & we went up to check it out. As soon as we entered bedroom we had the scariest,ickiest,tingling & goosebump feeling, but we still went to the attic door to open it. The closer we got the worse it got. Then Karen said,"I just heard someone say, I am up here." She said it sounded femalish in a whisper, but not nice. We didn't go in or even open the door, we just left and went downstairs. Wisth those kind of feelings and happenings, I came down and called & left a message for the one person that is helping us out & after that I called my cousin & his girlfriend because I was not venturing to that area or encountering anything alone, I knew better. Did that because Karen wouldn't go back up with me. They came, we checked things out. When we first went to attic it smelled like burnt plastic. We heard disembodied voices telling us to "get out", saying , "can you hear me" & "go away." Also while we were up there, I heard from our bedroom, which sounded like my oldest daughter, saying "Mom." It wasn't her, we asked, she was downstairs on comp. We came down & checked the rest of the house and we smelled stinking smells,heard voices pretty much saying what they said in the attic, but closer & louder. We seen dark shadows moving throughout the house,especially attic. We got nothing on camera(pics) & nothing on voice recorder either. So with all that, I believe the "nasty thing" decided to come back to the house or at least show some of its ugly appearence.Kenneth Kirk Jr. Forgot to mention also while we were checking it out the attic door was slammed against from the inside, scratching & knocking on it from the inside also.
