A Strange Feeling In My House!

I recently moved in to a new home with my husband and two young children. When we viewed the property everything was fine no bad feelings, been here a month and now getting uneasy feelings down in my basement is writing in red and weird faces drawn in red paint. I only get these feelings when up late on my own as my living room runs along side the basement wall. I told my husband about the feelings but think he don't believe in supernatural stuff. Can anyone give me any advise on what I can do to ease these feelings or am I just paranoid?. I get feelings like I'm being watched and goosebumps for no reason. I am starting to believe my baby daughter is picking up on the vibe she use to sleep all night in our old home since moving here she don't sleep that well anymore. I haven't seen any think spirits or other but got a constant gut tightening when near that basement door. I'm hoping for some help or advise I looked around online for some suggestions and this site came up. I'm at a loss as I don't want to move and as I'm the only one who gets these feelings with the basement does that mean I'm going mad. I sit with lights on at all times I often hear creaking floorboards coming from upstairs landing like someone walking back and forth. But that could be next door walking along there landing as the walls are quite thin. But from downstairs in my living room sounds like directly above on my landing. Hear constant noises from my basement like things being moved around. But that could also be the neighbours as our basements are right next to each others. Has anyone experienced the same as me I would be so grateful for help or advise. I don't sleep well right now and beginning to think the lack of sleep is what's making me crazy. Many thanks Emma
