Please let me know if I am overreacting. My son and I live in the basement apt of my parents home. There have been occasions where my son says that he is playing with a dog in the room that to my sight is not there. I didn't think anything of this because he is 3 and it is normal for kids to have imaginary friends especially at his age. One night he was sound asleep as I was watching TV and he started gasping and choking for air.. at first I just thought he was coughing but I then noticed that he couldn't breath.. he then woke up in fear crying.. I picked him up and asked what was wrong with him and he didn't answer.. I noticed that he kept looking into the corner of the room and I asked again what was wrong? What do you see? And he pointed to the corner and said I'm scared of that man.. confused I asked again and without blinking or moving he said again he was scared of the man in the corner that he pointed to.. immediately I put the light on and called the blood of christ to rid the room of any evil spirits.. I then moved upstairs with my parents for a while and everything seemed to be fine until last night... while I was sleeping I felt something grabbing my neck and choking me.. because I was so deep in a sleep I felt helpless.. this lasted for a couple of minutes as I was gasping for air I felt it getting stronger every time I tried to lift my body to awake myself the choking got worse.. please let me know if I am over reacting or there is some kind of spirit in our home ?
