I get up to get some water in the middle of the night. My wife also comes out to get some water. I was sleeping with my 3yo and she was sleeping with our 6mo. She says that she woke up, felt a cool breeze waft over her and there was this cloud over her and the baby, a dark black cloud that she felt was demonic and was just laughing at her. And that she felt she couldnt talk. She prayed and it went away. So I got some water, sprinkled with mantra, did arati to devi and siddhas and everyone individualy asking for clearance and protection, applied bhasma to everyone and lit dhoop, and said some prayers such as Shiva raksha stotram and devi kavacha. Things were fine for the rest of the night. I did same as a preventative measure the next night and everything was fine. I did nothing the next, but the night after that, I sat down to meditate a little before sleep (not sure how much was meditation and how much was sleep). I did feel a cool draft go over my feet. At first I didnt even care to look, but i remembered my wife and children, so I looked, but saw nothing and didnt feel anything negative. but my wife woke me up in the middle of the night to say the baby wasnt sleeping well,which happens alot anyway at his age, and that she started having nightmares again. she said the bed was shaking (something i have also experienced). So I put this before you good people for comments/knowledge/expreince/advise? Thanks to all in advance/
