My first idea, now, was mere surprise at the really remarkable similarity of outline—at the singular coincidence involved in the fact, that unknown to me, there should have been a skull upon the other side of the parchment, immediately beneath my figure of the scarabæus, and that this skull, not only in outline, but in size, should so closely resemble my drawing.†

coincidence = a situation where things happened at the same time by chance even though it was unlikely
I say the singularity of this coincidence absolutely stupified me for a time.†
This is the usual effect of such coincidences.†

coincidences = situations where things happened at the same time by chance even though they were unlikely
But, when I recovered from this stupor, there dawned upon me gradually a conviction which startled me even far more than the coincidence.†

coincidence = a situation where things happened at the same time by chance even though it was unlikely

coincidences = situations where things happened at the same time by chance even though they were unlikely

Definitions:

(1) (coincidence)
a situation where two things happened at the same time or in the same way by chance even though it was unlikely
(2) (meaning too rare to warrant focus)
Much more rarely coincidence can refer to things coinciding (occurring or operating at the same place or time). For example:
- the coincidence of a target and cross hairs
- the coincidence of entangled particles in quantum physics
