Check out one of my favourite subjects for example -
Synchromysticism is a study of coincidences, synchronicities, connections, esoterica, symbolism and possible hidden agendas in all aspects of reality.
Jake Kotze (The Blob) defines synchromysticism as:
"The art of realizing meaningful coincidence in the seemingly mundane with mystical or esoteric significance."
On the Dedroidify Synchromystic Blog we learn about the Esoteric through the Exoteric.
Don't just take my word for how good the site is, check it out for yourself if you have never been there before.
You would be hard pressed not to find a subject that doesn't interest you there.
