1:15 AM December 21. Shortest day of the year. About a couple of hours ago or around 11 i was hearing rhythmic sounds upstairs. I wanted to go outside anyways so i just went through the back and saw them upstairs doing something first i thought it was some fitness exercises. After 11?

They were two young women pretty close to the  floor to ceiling window, facing East, one of them quite slim and i thought i recognized AlexaCrush body from videos, bouncing on their legs with their hands extended forward, parallel to each other, palms down, and moving them up and down from shoulder and bowing like i saw in comedies when people mock giving praise to a person like to a god (could not find a name to that motion no matter how much i googled it).

I think they were laughing and i heard no music and there was also a guy behind them doing about the same but not sure. Could it be possible they were performing some sort of ritual?

2:00 Kinda like this but second and third pic, not that much (not touching ground or raising hands all the way above head, about half of the whole motion in picture 2 and 3).
