What about if you doubt everything?

When a child is told something absurd, she will say "really?"
and be willing to believe something that was meant as a joke.
Like "black is a shade of white,"  or something like that.
I hate it when someone lies to me at this point, so I always
say "no, not really."
But there is a moment of uncertainty, which can be used
for good or bad.  For example, it can be induced for purposes of
brainwashing.  But I use it in myself for purposes of healing.
I notice an absurd or painful thought, such as "everybody hates me,"
and imagine this thought inside a place of being unmoored, unstuck in
knowing things, as if I were doubting everything.  I think this place
sounds like a moment of enlightenment, in the tradition of Buddhism or
Hinduism.  A lot of times I see the thought turning into images like
a thick thorn removing itself from the walls of the space.
Next step: forgiveness.
