Seeing Patterns when Awakening at night

[LAB60]

Upon awakening at night, I see a grid pattern, black, once red,   The size of the grid can be a small spot on the ceiling or becomes larger and covers the whole ceiling.  The tv is on and provides some light in the room.  After blinking a few times, the pattern goes away.   The pattern is more frequent and has increased in size over the past year.  The eye dr. said he never heard of anyone seeing this and felt there was no retina detachment.

Not sure where my earlier comments went, but I was saying it can't be natural to see perfect grids. Apparently it can.
  Migraine aura can produce grids and checkerboards
Competition between different images received simultaneously can produce a grid pattern, usually diagonal.  My eyes are currently mismatched after my cataract removal, so maybe the messages were competing in my visual cortex, producing a kind of interference pattern.
And psychedelic influences, or electrical frequencies firing off at around the rates of natural brain frequencies can cause you to see such things.  Not mad, perhaps sleeping near too many Electrical devices?  No idea!

I would be surprised if regular exact grid patterns were the product of nature.  Surely they're not a brain construct?  Perhaps an after image, but then you'd have recently had to be staring hard at a mesh just prior to seeing the aberration. This is weird.  It sent me looking
I have middling to high blood pressure, so it's not due to low, as someone else said.

Still no answer about my seeing  a green grid on my ceiling when waking up.

I awoke to see a perfect grid pattern, dead straight lines.  I have just had cataract surgery.  I am wondering whether it was done with a femtosecond laser and I am seeing a projection of the grid pattern it makes to break up the old lens, left behind in the cornea.  I had a general anaesthetic, so I'm not sure. Only seen it once, thank God.
Flashes can be due to posterior vitreous detachment in an older eye.  I've had that too.  Now I'm getting flashes from light escaping from my new lens.  It's jumpy and reminds me of aura migraine.  Hoping my brain learns to filter it out.

Me also.  I saw a green grid pattern on my ceiling.  I woke and lay awake and stared at it for 5 mins.  It went away when  i got out of bed.

I have this same thing usually daily upon wakening with my eyes still closed.  I also have a host of other neurological and visual ailments. I have a positive IGX laboratory Western Blot Lyme Disease test result for Borrellia, the Lyme bacteria and I'm infusing an IV at home as I write this. If you also have pulsating eyes, floaters, squiggly things in your vision, black spots and periferal flashes or blurbs, consider Lyme and or the many co infections of Lyme such as Babesia Ducani WA1 and Brucella, which I have too (ARUP Labs), which cause numerous physical symptoms. Check out CanadianLyme.Com or canlyme.com for a vast symptom checklist.

I have been seeing a grid when awakening in the morning. Goes away in a few minutes. In the last few months this only happened occasionally now is almost daily. Eye dr. not sure what is going on but will see him again next week. Any new info on this?
