Dream Symbol

Its a symbol i saw in a dream i just woke from... The dream wasn't a nightmare, but for some reason, it was eerily lucid; that's why i take it's meaning to heart.

"REPT" as seen in the bottom corner is not a real word, i looked it up, but as it was told to me in the dream, i said to mean "peace" or "silence"... After i was taught that word, my teacher held up a giant likeness of the symbol i tried to depict above... In the dream, it was just a foam prop (as i was in a theatre class), but since the dream was lucid, it was eerily foreboding. My Teacher, Mrs Mayfield, said the the symbol was said to mean "God"... as you can see, the symbol even has a spelling of the word immersed in it, as well as an eerie resemblence to the greek symbol "OMEGA", but that's not the point...

The point is that this symbol instantly struck fear into me, without even hearing what it meant. I have no idea what it is, or what it's connection to the jibberish word "REPT" is, but i just say to you, be mindful of it. If you ever see anything similar to it, take caution.
