[FairfieldLife] tiny speedy particles visualization at start of video???

[srijau]

does anyone see in their TM a visualization a lot like that of the tiny 
streaming particles at the start of the video? I get this in complete darkness 
and something like it in very bright light   would love to have some 
explanation of what is going on.  Have heard some theories but would love to 
hear if Maharishi made any comment on it or anyone else's idea. please and 
thank you
