Interestingly teasing answer, but I really meant experiences in general.
For example, how do you distinguish between real memories and dream memories or false memories?
If you believe that some dreams come from outside yourself (do you?) how do you distinguish those dreams from ordinary dreams?
i'm sure some people are going to jump all over this but i really don't try to. in a lot of ways, trying to figure everything out, and interpret these things is what can drive me nuts if i let it. my experiences have been so varied but it all comes together to have meaning. if i try to force the meaning, i find that it is counterproductive.
in regards to dreams, i've had recurring ones, with a recurring theme anyway, and i've had very lucid ones on a few occasions. i never understand the dream when i have it. but in regards to most of them i remember (which are relatively few), when i look back on them after i've had certain experiences, they seem to be telling.
there are times when it's like a 1000 coincedences have profound meaning, and this is over time and general and all inclusive to other more specific experiences. there have been specific times when i've actually received a specific message seemingly telepathically, like an impression, and other specific times when it's very concise and verbal, but also in a telepathic way. there are other specific times when much more trippy shit has gone down, like transcendental writing, physical manifestation of something seemingly inhabiting my body, being aware of spirits around me, either by some knowledge that i have no explanation for, or by experiencing a physical sensation in regards to them (like an interaction), or one very trippy time when i actually had physical objects in front of me morph, with no other explanation whatsoever.
all of these things i've been through have meaning, and in relation to one another. not only that but the experiences themselves and the meaning behind them, have done a great work in me. developed me.
