Joe,
What you are describing reminds me of this strange thing that happened to me once...
lying there in bed, half asleep.... when a ringing in my head begins to turn on like a switch...
when i start to open my eyes i notice that the room was starting to get brighter the more i opened them...
it was like my own personal night vision.... I wasn't fully aware how this was at all possible... but it wasn't alarming....i was conscious... but I don't remember what happened after this... strange i know... haven't come across any other story like it.. but yours is similar...
Strange ability being able to see in the dark.... wish I knew how to turn it on all the time..
