when im meditating the most common thing that happens is when my eyes are closed i can see my hands or laptop or whatever is in front of me for a few seconds.like i can see through my eyelids.. kind of like the character henry sugar in the roald dahl kids books if your familiar...
i only started the technique last week ... and my brother the same , and he got the same sensation .. i looked it up and all i found was somethin bout "3RD EYE" im not familiar with any of that theory.
but i dunno really .. is there anythin at all you have heard bout this ? cos i cant be imagining it if my brother is getting it too . its very slight though.
I've had that experience a couple of times ... seeing the bed cover I was sitting on while meditating. It was a while ago though, and I cannot be 100% if it was THE bed cover or just a mental image of it.
