Texas sharpshooter fallacy

Painting the bullseye after shooting, or forcing data to tell us what we want.

Source, wikipedia
In the Texas sharpshooter fallacy unrelated information is interpreted, manipulated or disguised until it makes some kind of sense. The name comes from a joke in which a shooter randomly shot at a barn, and after that he painted a bullseye around each hit and claimed to be a sharpshooter.

Someone dreams of number 7.
Number 7 didn’t come out, but number 362 did.
Nonetheless the premonition gets confirmed by claiming that 3+6-2 equals 7.

To refute it
Generally speaking, proving it is a fallacy could be relatively simple if we find a way to repeat the experiment. For example, in the case of this drawing, we could easily propose an alternative constellation of stars.
