I think the dolphin is enjoying it, but the goose (or is it a swan?) appears to be looking down in a disapproving manner... Unless it's just envious at being left out?
Totally relate to the 'wanting to sleep in it', I've felt the same about my favourite place, except that the incoming tide wouldn't make for a happy ending!
I've done this (accidentally and otherwise) with the old Mehron-oil mix many times. It blinks out really quickly, but don't do it while wearing contacts - you'll ruin them. They're porous, and the fine metallic powder gets into all the holes, turning them gold or silver.
Dried acrylic feels like a thin, plasticky film, which is nice, but I always found it to be a bit dry and crumbly after a while. I've never been able to sleep in it. Adding some rubber to the mix gives you a flexible coating that squeezes you all over. It's also hard to sleep in, but for overstimulation reasons.
