Aliens in my attic?!

I have been hearing things for the past couple of weeks like sounds of something walking on my roof and whispering.  Last night at approximately 7 pm my boyfriend and I were out in the camp trailer that I have been remodeling.  We finished out there and we were heading back inside when I saw lights over at our fiends house in the back like flashlight looking.  I got my phone out and staring recording while I held my flashlight so I could see. I have been seeing thing and hearing things for weeks and no one has really believed me so I have been trying to capture it on video.  Well anyways I saw what looked like people with black clothes and ski masks on and they were on the neighbors roof.  We let the neighbor know and went inside.  When we got into the house I see lights outside the house and they are like flickering.  I get out my phone and I start looking out the windows in the laundry room there are three different windows.  What I see shocks me and i am at the p! oint where I don’t believe myself anymore because everyone else thinks I am seeing things.  I see things on my neighbors roof jumping up and down I see creatures of some sort in white suits and I see the upstairs of my house which is not a part of the house and is only full of insulation and not live able have a window that is not supposed to be there open with lights on.  I continue to film them and then I got scared that maybe I wasn’t supposed to be seeing them and they saw me videotaping them so I shut the curtains and came back inside.  But I have seen them before and thought my mind was playing trick on me because I just feel like this is too unreal.
