When i wake up, while i'm still tired, when i open my eyes, i see my vision snapping from double vision into normal single vision.
While in this state of tiredness, if i close my eyes (even just to blink) i can feel my eyes go misaligned and as soon is i open them again they snap back into alignment.
When i get up and stop being tired, the problem is gone.
This has been going on for years, but didn't think to much about it because in the beginning it snaps back in a split second and there where no additional misalignments when closing my eyes. (It still snaps back in a split second but noticeably longer).
I sleep on my back on one of those weirdly shaped pillows (because of neck and back issues).
Should i be worried, is this normal? I am 28 years old.
