In qi gong when the body starts to fill and pressurize with qi the arms will often start to float up, this is pretty common. The instruction is to keep them down so that the pressure is directed inside to open things up and create space . If you allow them to float it is less efficient (and it’s also kind of weird for others to see, haha).. It is a funny experience to have, particularly the first time but you get used to it. My suggestion is smile or giggle a little so you don’t take things too seriously and then just keep practicing without giving it too much thought. It is just part of the process of change, don’t get too excited or attached to it as this will slow the change process.
