Get up out of bed and go pee.
it means that you have been holding it for too long...go pee
This is just too weird. I've never heard of such a thing.
It means that you have a space alien chip implanted in your head and the waves and water thing is your psyche, wanting you to test and see for sure if you have one. For the test, stand on your head in the commode and flush. If you hear rushing water and waves you undoubtedly have a chip in your head. For chip removal instructions send me a bucket full of twenty dollar unmarked bills and SASE. Allow ten days for this thorazine shot to completely wear off.
It means that you just wet the bed.
You should of peed before going to bed.
Surf's up, grab your board, and head to the beach.
You just peed yourself and your water bed broke..
Well it depends on who you are. It could mean that you are a surfing enthusiast. Then again, it could mean that you are a scientist too. lol :)
