First audible,then visible & then digusting feeling

We were laying in the livingroom with all lights out except the light from tv. Karen heard what she thought was our youngest daughter saying that she couldn't sleep. I went upstairs to check on here and she was sound asleep snoring in her older sister's bed. I put her in her own bed and came back downstairs to continue watching tv. About a couple minutes after that we heard noises coming from the diningroom area. I got up to see what it was and standing by the doorway that connects playroom and diningroom there stood this solid small black figure,about 4 ft in height. I told Karen to get up and look at it real quick and it just stayed there and she seen it and said oh my God and backed away a little. The feeling of it being there wasn't to great. I then turned on playroom light and it was gone. I was hesitant to go out to diningroom to turn the light on out there, so I asked Karen to go with me and she wouldn't. I built up the courage and went out and turned on diningroom and kitchen light on and while in both of those rooms I got a sick/disgusting type feeling. I turned the lights back off and came back in through and haven't heard,seen or felt anything since.
