text that you read in dreams
tends to be different if you re-read it

this is because the brain spontaneously generates words to fill spaces where it tells you there should be words
but then junks them once they've been read

if you read the text again it's changed

if you realize this, you can have a lucid dream

freak out!

but once I dreamed a spoken word poem
dreamed the sounds, not the words,
and it stayed consistently the same

geek out!
