I am not RLR  but that sounds like a Migraine.  periodically I have the zig zag lines in my vision but thankfully do not get the headache.  Do not know what the numbness would be though.  Perhaps you should see your Doctor.

Okay, you need to remain calm. Also know that I am not able to be on the forum in a continuous manner, so please don't expect an answer when in crisis. At 87 years old, I have limited time to check on the forum and respond. If you experience imminent health concerns, you must always first seek a response from real-time medical personnel within your local or regional community.

To address your question. the phenomenon described would be classical migraine syndrome and the visual manifestations are known as fortification spectrum. The onset of the spectrum typically demonstrates a small area in the visual field that might be blurry or altered from the rest of the visual field and soon a small "C" shaped fractured glass of various colors begins to form, gradually extending farther into the visual field before disappearing from view about 20 minutes or so later. In classical migraine, a headache typically follows. In cases where the fortification spectrum appears in the absence of headache, it is known as optic migraine.

Numbness in the limbs can in some instances be due to migraine syndrome, known as hemiplegic migraine. I doubt this was the case where you're concerned, however, and more likely due to mild nerve compression by body position during sleep.

You need to try and relax more. You're far too young to be so nervous and apprehensive.

Best Regards and Good Health
