They are special in a way that they feel different and are uncommon.
Good. Honest. Now look again.
What makes them “special”?
Without the labeling are those moments actually different in what they are?
Or only different in content and interpretation?
When "thoughts take over" there is nothing else experienced than them.
Right now don’t rely on memory... Wait for thoughts to become active again then check, in the middle of it:
Are thoughts the only thing present?
Or, at the same time:
is there still a faint sense of the body?
is there still sound in the background?
is there still visual field (even if ignored)?
Is it true that thoughts replace everything else? Does experience disappear?
