Which may or may not have lifted it right from the “Batman: Legends of the Dark Knight” story “Masks,” complete with “is (s)he or isn’t (s)he ending”. 
Yeah, exactly. That gave me the shivers when I read that.
Now I see that there is good and bad news in this thread.
Good news: At least we’re not alone in thinking this stuff, and I don’t think it means we’re nuts.
Bad news: Although we may not be alone, or nuts, it’s possible that this stuff we think is true. I honestly try not to think about it too much, but sometimes you just do anyhow.
I think I have all that have been described, but something else as well. Every now and again, I “come to” and realize that I am talking and explaining something and I can see the effect is has on whoever I’m talking to, but I’m also outside of it, or rather, inside of me, watching it, hearing myself or rather, listening to myself. And it leaves me with a feeling that since these times only come every now and again–could I be doing something else entirely all the rest of the time and not be aware of it at all? Like my life is some kind of alcoholic (I don’t drink)blackout with only spare moments of lucidity—or is it the other way around? I have often had the “this is a dream” feeling–I think I have it more than “this is real” feelings.
I also had the oddest feeling the other day. I was walking outside and suddenly had the perception that I was only eyes and mouth and hands. I don’t know if this is really what Freud was talking about re infantile stage, but I felt like an animal–less than an animal, just a blob with eyes to see food, hands to procur it and a mouth to ingest it. But it wasn’t about food, per se–it was everything, like I had turned into a huge I WANT THIS/THAT creature–consuming/grabbing everything in my sight for me–feeding the maw (food, “toys”, joy, everything)
It passed as quickly as it came upon me. God knows what it was. Some days I feel like I am truly cracking up and not in a funny, gee it’s an adventure to get old way…
Correct me if I’m mistaken, but this whole concept is all very Zen, isn’t it?
Or, “Duuude – you are the bodhidharma.”
