The other day, about a week ago, I was out to eat at a restaurant with my family. As we were eating, I was looking down at my food, and while I was doing so, in the upper part of my field of vision, somewhat like being in the corner of my eye, I thought I saw someone wearing white doing the preparation of doing a handstand, like placing one foot slightly in front of the other and then lifting their hands, bending down and doing a handstand. I looked up, and the person disappeared, as if they were never there. Was this some sort of hallucination, and I just saw something that wasn't there? The other possibility that I thought of was that I saw someone who was astral projecting into the restaurant. But I don't know if this is something that is even a possibility. Has anyone experienced anything like this, or does anyone know why such a weird and random thing happened to me? I have had so many strange experiences like this lately. Thank you.
I should also mention that three weeks ago, I had a right craniotomy and partial resection, which is a brain surgery in which a part of my brain and a small benign tumor was removed. This is when a lot of these experiences including empathic experiences which I have written about started to intensify immensely. While I was feeling my own pain in recovery from the surgery, I was also feeling the pain of everyone I was close to physically and emotionally. I'm desperate for an explanation for all of this, but I don't know where to start. I don't want doctors or other people to think that I've gone insane, because I still feel total clarity and lucidity. But at the same time, I worry that I have. There is just something STRANGE going on, and I don't know why. Again, Thank you for any help.
