I've been having sporadic, millisecond-long experiences where I associate the word "I" with the Universe rather than the body or the brain. Most of the time when it occurs I start sporadically laughing from my belly, but sometimes I start feeling lonely instead. It's along the lines of truly feeling "I" am the One. And if I'm the One, even if I have lots of other perspectives (other people, etc), there's really nothing else. It's just I, and it makes me feel lonely. I'm assuming whatever glimpses I'm getting are illusions rather than waking up, but I'm honestly confused. Is this a normal feeling on the path to enlightenment?

For clarification, I'm not talking about loneliness in regards to other people. I'm talking about loneliness as the One, knowing that I am all there is, and there's nothing else.
