Ok an update on my experiences: a few days ago I sat and had less wandering and odd visuals, and then I had a strong tingling sensation starting at my neck and running down my body. Like shivering but no actual body movement - stronger than my previous tingling and different. This one travelled through the body. This happened over and over about 10-15 times. I was noting things like happy, calm, excited. It was pretty enjoyable, almost sensual. I was not aware meditating can produce these odd sensations. It's very interesting. Since then I have had a small amount of that but not nearly as much. Also I am easily irritated afterwards and am now a bit anxious. I am also noticing small jerks and stutters in my breath. It's chunky when I focus intently on it. Also getting these things where I suddenly realize "something" happened like I fell asleep and woke suddenly. Also today i was looking at myself in the mirror for a long time and then it was like my face looked frightening to me and there was actual fear. Very interesting. I was skeptical but this is producing bizarre effects and I'm bored so I'll see where this goes and keep investgating.
