I’ve been Keto for just over a year, and there has been some differences. In my case I’m a little worried about it.
For several years before keto, I have had semi lucid dreams. Not a full on dream state per se, more like almost asleep and the show is starting early. Quite literally looks like a small screen in my eyelids. Covering a small area of about 16 square inches at arms length away. But I don’t focus my eyes on it, it stays in focus. If I turn my head the image moves as if it’s anchored to the spot in space. I once began to see another image appear from behind me but never saw it completely. Always in normal looking color too.
I have an idea of why. I think it might have been my blood pressure meds causing this. They began the same week as starting metoprolol.
After going keto something new happens. I don’t always get these images when falling asleep. But I do always get them right after waking up, if I do a stretch. You know, full body push out the legs and shove hard. When I do that, I get what looks like a small window fade into view, or more like a small tv screen. Fades in, I can see it clearly, and it exists for maybe 5 seconds before fading out. Gone until tomorrow.
In both cases this image disappeared as soon as I would open my eyes. Close my eyes and it’s gone still. Then one morning, I was laying on my side facing the window when I woke. I had my eyes open, I was looking out the window, and a second window appeared on a blank spot of the wall. It had full continuity with what should be seen if a real window was there. The lighting was different, more sunlight, and dinosaurs. Yep. There was a T-Rex standing in my front yard pulling weeds, it looked like. Further down the street, as this window would look right through the intersection (my house is at the top of a “T” intersection) I could see more smaller dinosaurs wandering around. But again this lasted just maybe 5 seconds before fading.
Now the one that worries me. I have been worried about this happening too. I woke up, the wife was already awake and putting on her coat. I sat up to ask her why is she heading out so early, she looked right at me and vanished. The she answered me, from right beside me. I had just woke her up, so I played it cool and sai, I didn’t say anything. You must have been dreaming. 
All of these dreams or hypnogic episodes never had anyone I knew in them until this one. Always people I don’t know in places I’ve never seen. Couples eating food at a table, parking cars right in front of me. Parking aircraft right next to me (including jet noise).
I have had on occasion been able to control the action in the little windows. Essentially behaving like a remote camera repositioning or panning. I once did make the a car in one of these lift off the road and flip over.
I’m seriously thinking of looking up a shrink if I continue to have any more of these episodes while awake.
I beleive there is something to this stretching I mentioned. I could wake up and lay there for 20-30 minutes and not see one of the until I stretch. Sure enough there it it. And what gets me is how this figment in my mind can be anchored in 3D space.
