Its been shown in studies that over a certain mg amount, and this highly depends on tolerance, or lack of tolerance, that too high mgs doesn't give the three day relief that this stuff is prescribed for. Sources The Huberman podcast Ketamine
as far as bright lights, I once did 125 mgs ketamine and lights were so overwhelming I just about became sick and had to close my eyes. Ketamine clinics put a mask on and keep the setting with low dim lights
The above and Tim Ferris's podcast with a leading ketamine researcher Dr John Krystal are some of the best information ive read (along with some reddit users posts, and here on bl)

Viraldrome yes too high doses causes weird thoughts, and is not worth it , in any way for therapeutic benefits, in fact it causes the positive effects to be lessened or gone. Again this is covered in the huberman video above
This is my experience as well, that when things get above a certain level, thoughts become weird. For example I did 125 mgs and was way too intense. Another time on a 100 mgs fxe dose I became unconscious then came back and tried to wiggle my third toe. (this little piggy ate roast beef) and couldnt. my legs were crossed and I convinced myself I had to keep my legs crossed until I wiggle my third toe. My parents were on vacation and coming home that evening but I didnt know what time they'd come in. I couldn't wiggle it, (I dont think no-one can its an extremely difficult thing to wiggle your third toe beside the pink toe, unless practiced a lot) I convinced myself again that I would stay on the couch until my mom came then I would ask her to wiggle my third toe for me (I can be super patient) finally Parents came home , I realized that action beats anything I got up, and took a cold shower (a cold shower helped the numb face, eyes that fxe gave me, and also good for waking up and supposedly joints)
on a smaller dose, when not going too far, a movie can be an immersive experience, where you feel connected to a character, and someone you once felt deep for. For therapy though music and closed eyes and dimmer lights, even dark, maybe is ideal .
my point is when thoughts become like this, its too much. When you can close your eyes, focus on your inner world and music , is where I seem to get the most benefits, just lay there an hour untill that floating walking feeling is mostly over or over. This is where therapeutic benefits are. Going too far like I did with the piggy toe story on weird thoughts is not beneficial .
I dont understand why some psychonauts want to keep going too far , if something isn't beneficial and thoughts become weird. I crossed the red line going too high in dosing and am conscious of this. This is why starting therapy dose is 0.5 mgs per kg for most patients without tolerance at ketamine clinics (iv which is 100 percent)
