BBQ shark

Date: 9/19/2016

Movie 1/3r person view, Family reunion/holiday get together like 4 of July or something, my dream family and I are at an old man's house who secretly has a lab under his house that is actually so far under ground that it's under water, a group of the family including me and my grandpa (who I call papal) find our way to the secret lab/research facility. As we are inside of the lab, on the earth's surface flooding has started do to some unknown reason. Our group is now stuck inside of the lab and the water pressure is building within every hour due to the rise in the water level. A undiscovered prehistoric shark reappears and for some reason we call it a BBQ shark. The shark was massive it had thousands of teeth and where it's tail would be it had a second mouth. Someone tried to go outside of the lab in scuba gear and a small sub to get help but he was attacked by the BBQ shark. But before he died he cut the shark all the way down it's back cutting it open but this did nothing but make the BBQ shark angry and now it has turned itself into a giant mouth (also Rob Riggle was there inside the lab) but the water pressure continued to slowly crush the lab. Somehow all but 3 or 4 of us made it back to the surface and back inside of the old man's house (who I'm just gonna call grandpa for now but he's not my grandpa). Grandpa was standing in front of a huge window watching the flood waters rush down the streets and as Rob riggle yelled for him to get away from the window the BBQ shark burst through the ground and broke through the window and ate grandpa. The rest of us ran outside to escape from the BBQ shark. As our fucked up looking family ran down the street we came across an abandoned bus in shallow water so we all piled into the bus and took off. Looking for high ground and on our way down the road we see signs and hear on the radio that Las Vegas was safe so that's where we were heading, and then I woke up.
