These dreams are very different from your normal dreams, you see. It's quite interesting.
Instead of it being a dream, it's more like you're actually there. Like you're an actor in the show instead of watching it in a theatre, see. So the dwarves in the dream seem very real. You can reach out and touch them, speak to them, cuss at them and call them names.
Well you can't really do that last thing unless you're hoping to start a fight with the local merchant's guild, but still.
