Two things,

1.
You didn't fully explain your eyes "re-adjusting to light" and I believe you may have the wrong conclusion. That topic covers twitching eyes but the process of switching from Daytime to Nighttime Vision has nothing to do with the twitching of the eyeballs. It deals with the pupils. During the Night your pupils get increasingly larger so that they can let more light in and see more. When you suddenly turn a light on from a dark environment your pupils are large and let all this light into your retina which hurts.
Not sure if you or others knew that but if you didn't than there you go.


2. When I experience the wave of SP, I dont go into SP....The "wave" of SP wakes me up and i snap out of it real quick. I am not afraid of it but its kinda just random and quick and so it wakes me up.
