The first sensation I can remember is this swaying feeling. I was in the “Ocean float” room, which you can move around relatively. This swaying feeling didn’t seem like the actual physical swaying. More like the residual of the physical one in my mind and my body. It reminds me of the lady in white dress in Japanese horror movie Kuroneko in 1960s.
It was hard for me to get into the mood. I think I got up like 2 times. I can’t remember why I got up the first time, but I did the second time because I was feeling noxious. Kind of like carsick or seasick. Probably because I was moving around with my arms quite a bit. I think I got the hang of it the third time in the float. I even felt asleep a bit, but got up right before the music started because some of the water went into my eyes slightly.
Hopefully, the next one is more of a smooth ride.
