I'm sure a lot of people are as obsessed as you, the reason why this forum was ever created. I'm not too obsessed in it too myself currently, but I hope to get more enthuestic with it soon enough.
Well, being obsessed itself can't be any harmful by itself. If you take various drugs and pills just to get LDs or doing some specific things that could be less healthy for the enjoyment of it, it could get unhealthy. If you get unhealthy also, and become (hopefully not) depressed, you would have less will power to have more dreams...
