I had a dream about fighting Gs

At first, it was just Gs. It was a stage-clear type of game where you faced enemies with just one can of spray. It started with just Gs, you know. I remember the small brown ones and the big black ones. As I cleared stages, more obviously dangerous creatures started appearing. And I remember a horseshoe crab showing up too. Yep. I defeated it. Besides using the spray as a chemical agent, physically, I also hit them with the bottom of the can, or hooked the trigger part to knock them down. It was somehow... Unbelievable, yet strangely... It felt so 'real for a dream'...
