If you think that’s ingesting, look into silent migraines.
Essentially, you get all the physiological issues with migraines except the pain.
So being sensitive to light and sound, loud noises, nausea, the whole shebang, just no pain.
Also, interesting bit of theory, in Alice in Wonderland, the growing/shrinking and dilation of space is thought to be a side effect of migraines and its thought the author suffered from them.
Its actually called Alice in Wonderland syndrome.
I’ve experiened it myself, if your heads been fucky and seems like that hallway got longer, or that road got shorter, it could be a side effect of a migraine.
