I was photoreading this afternoon and I think I'm starting to understand when everyone means relax and just let it happen, but that's not what I came to say. Well, when I was photoreading, I started to feel very light, also, there were two points on my upper chest where I felt like I was very light and energetic. I thought it could be one of two things: it could be a side-effect of the photofocus state, possibly just intense concentration, or it might just be hyper-ventilation. I'm not sure about hyper-ventilation though, because I was breathing slow, I thought anyway. Has anyone else had that sensation? Anyone else's thoughts on this?
