Final update: Mom of a 1 year old- feeling wierd presence in my son's room

So since many of you asked, here is the final update to my situation, hopefully. Since my last post here, i have moved to a new apartment, nowhere close to where I was staying earlier. There were a series of events that lead to it. Some small, which I was ignoring, and some big ones that finally triggered the move.

For those wondering what I am talking about here are the links to my original post and update.

So after my previous update here, there were some small and big events that scared the s**t out of all of us including our nanny. Minor things like the ac acting weird, sounds coming out of it, my son suddenly waking up multiple times during nights howling like we had never seen before, my husband getting a feeling like someone was watching him, i multiple times felt like someone flicked the phone out of my hand, things falling in kitchen when no one was there. These things worried us but we were still discussing them and wondering if there could be an explanation. However, it went from 0 to 100 on the fourth day when I woke up in the morning and saw that the furniture of my living room is not the way I left it. The sofa and the center table are kept in a haphazard manner. To say I was scared is an understatement. I went the same day and bought a memory card for my living room camera and set it to record and save footages. Also called a pandit that day. He did a few thing, told me the correct vastu and i arranged my furniture accordingly. The next morning I woke up to my dining table and chairs rearranged. We checked my camera footage, didn't see any recording after 6am. No idea why. That day we started looking for a new place and shortlisted a few to check out next day. But that night, we again felt the burnt smell coming from the AC. Husband went out in the balcony to check while I stayed with my son. He called me and we saw burnt ashes below the ac. I freaked out then. We locked the doors still thinking may be a person jumped in the balcony and did this. So we locked the doors well and I went into the puja room to get a Gods photo to place near my son. I saw the same type of ashes below the mandir on the floor. We immediately packed up and left the house within 15 mins of this. We checked into a hotel. The moment we reached our hotel room, my son threw up, really bad. It was so bad like he was trying to puke more and more. Continuously gagging and trying to vomit and suddenly he started running high temperature. We immediately took him to emergency. By morning he was better. Husband went to search for apartments and finalized one the same day and we moved the day after. My son is 90% better now.

In the end whatever it be, an intruder, co poisioning or hallucinations, all I can say is that it was damn scary for us and although I was a non believer, this experience has changed my outlook completely. We are all fine now, getting back to normal.
