Dagon? Options

I dreamt of the past. A group of witches was fleeing Dagon, but could not escape. Because everywhere they went, Dagon followed. Then they traversed forward into time when Dagon was weak or no more. They happen to bring a person of Dagon, I'm not quite sure what or who he is; the witches knew he had an undetermined destiny, whether good or bad, they gambled that his power would be to their advantage. I say witches, not the sterotypical black cloths and hat, I suppose they dressed like typical folk maybe even peasant like in whatever time it was, except for that they could use magic.

Dagon? An HP Lovecraft horror? Or Semitic God of farming? Could you elaborate a bit on what you mean by this creature (or deity) please?

I heard name Dagon before but now I know why it was for you not me when someone yelling Dagon ,Dagon from the door with his hand out , inside a some house
like Crazy one :/
