A Haunting I have been having

The past two weeks some major things have been happing, first it started off with something walking around in my sons room about 2:30am, then every night that week 2:30 to 6:00 every morning something was happing to my son. I heard a loud noise in his room and he would feel something grabbing his blankets off. Not only that the dog would just be barking at nothing in the kitchen and one night I went to check the house after the noise and all the lights in the kitchen blew out. And every night we were having nightmares.
Well I was tired of it so my mom gave me some sage and the kids and I did a cleansing in the house. It was our first time we said a prayer and told the darkness to leave and that they were not welcome in our house and sage everyone even our pets and every room. I think it work the kids slept well for the first time and no nightmares. Well for them I seem to have them all the time.
After the cleansing I heard a few times outside like something trying to get in the house like always I check the whole house made sure the doors were locked and nothing was in the house and prayed like I do every night. Last night my dog went crazy barking at nothing again. I guessed I’m getting freaked out again if there is any advice you can give I would appreciate it thanks.
