Happening in my flat

My son experiences cold spot in his room.
He also experiences cold spot in the kitchen.
He had been pressed a few times.
He legs had been hit many times.
Once he saw me talking to him in his room, at that time I was at work doing 8pm to 8 am shift.

My daughter heard voices in foreign languages voices of men talking.
She found her son crying and told me looked like something disturbing him.

One day my two Scottish terriers ran out from my room, I ran out of room and my daughter ran out of her room, we saw a black thing coming out of her room moving pass my room door. All of us ran out to check at the same time.
