is my house haunted?!

ok my brother says he sometimes hear things...i sometimes feel something on my leg...my brother even detto he sometimes feel something on his back....i sometimes feel breathing..or like wind on my neck....my parents dont feel o notice anything strange other than them not finding things and my mother is a great at looking for things....i hope this was an imagination but my brother once told me that he has seen little dark shadows running down our hallways....and once....i took a picture of myself.....and right successivo to my face was another.....i just hope it was the light shining on something...now before te ask "How old is your house?" o "Check the history on your house" My house is new...the whole neighborhood it new....in fact they are still building alot of homes...and we are like in the middle of a forest...like really....but there are like hospitals and HEB a pharmacy. now if te live in USA in Texas near houston and te have seen sugarland and such its just like that only...with più and più trees....anyway yeah...i so hope that my house isnt haunted....but is it?! i need to know!
