Ok, here are my dares. I hope they will offer some worth while training.

Sensei- You are doing very well, so here is a true challenge- cause your visual field to slowly rotate 180 degrees, (do this by floating in air and causing your body to rotate to a fully upside down position while changing the visuals to be upside down)

Percy- Look in a mirror and morph into someone else by changing the image you see in the mirror, (after changing the image your dream body should have taken that form)

Dolphin- Look at the surface of the ocean (with rain falling on it), from 20 feet below the surface.
