Yeah, I don't see it as a problem at all, kind of cool too. I had one a long time ago, when I was f2p and it was still the rs1 days, which was something to do with me finding a rune med spawn in a cage in varrock and I managed to telegrab it. Recently though, I play runescape alot, and typically right before I'm going to sleep so I'm not surprised I been dreaming about it more. I still seem to have regular sort of dreams though, which I find even more interesting because now I can distinguish between the two dreams in a way, whereas before all my dreams just jumbled together. I don't think it's sad to be dreaming about runescape, for anyone who thinks it is, like abyssal said your imagination does all sorts of things when you're asleep and you can't control it.
