Last time I checked there aren’t nerve endings in our brain, so it should be impossible to feel sensations in my brain. However, at random times during my life, like seeing the plot twist in Fight Club for example, I’ve felt feelings in my brain. I just felt it again now while doing some intense introspection, and I just wanted to see if anyone else has this happen?
Maybe check your vitamin levels and make sure you’re drinking enough water. Sugar is dehydrating, a general rule I follow is drinking 2 cups of water for every cup of something else.
