This is one of my recent experiences. I recently moved in my parents' flat. My dad works abroad and my mom was living with me. It's been years since we bought that flat and started living in it. We never really got to live in the flat for a longer time, as I too studied abroad and not in India. We used to come by the least for a month during my vacations. This time, we are moved here for good, to settle down.
We had gone to family friend's house (call her Ella) one late evening. While my mom and Ella were talking, the topic of our building came up. She said that she knew a lady previously who resided in the flat next to ours who experience something. It was absurd, but didn't scare us of much, because we were into prayers. She also mentioned to us that people hardly reside in the building because they think it's haunted.
We never thought that it could be so as we had nothing happen to us.
Then later that evening after we returned home, I was trespassing in my balcony. It was about 9.30 or 10 pm. I went to one corner of my balcony. From here, you can see my neighbour's balcony easily, and the one beside it is not in clear view.
In a few moments, I could see a number of white cloud-like shapeless figures fly from the flat (one which is not in view) through the sky and into the trees. It continued for a couple of seconds. I tried to peep through my balcony itself to find out what was going on, but got nothing. It couldn't be from the headlights of the cars because it was very high.
I tried to take a video of the scenario, but by the time I put it on, it happened no more. Then after a few minutes, I saw one of the same white cloudy thing go to my neighbour's flat (one in view). This got me more curious. I didn't tell this to my mom that very moment, as she doesn't believe in any of this and gets scared.
Later when I got to sleep, I couldn't get this out of my head. Somehow I couldn't find a reasonable explanation to it.
