If you had a realistic dream where you make a 6 sigma measurement that goes against the standard model of particle physics,
where every other group of scientists confirms your measurement, against any existent current theory:

1 - You should assume the standard model to be wrong.
2 - You should assume you are dreaming.

Which one is true?
Also, how do we effectively know we are not falling trap to some kind of mind bullshit like this right now?
