I just have to mention here something about Phiedpiper and his problems.
Back at the and of 2007 / beginning of 2008 I've had very similar symptoms for about 3 months (which occured as my heart chakra started to open, as I understood later).
After reading his words:
...my eyes just lose focus...
I must say, this is exactly what I experienced:
-my eyes losing focus
-during loosing focus, I sometimes didn't knew where I am, or who I am (for some 4-5 seconds of time)
-loosing my balance, a feeling of falling down.
My doctor found nothing. And after it all finished, I was quite more "open" as I used to...
So if you read this Phied, please know it is nothing you should worry about. I would say, take this expiriences now as they come.
I wish you all well.
