Dream of girlfriend

Not sure where I am but I find myself going through a house looking for a bathroom because I have been vomitted on. I go up and down stairs trying to find a bathroom and it seems everyone I find is taken. I go out a door and my ex husband and his girlfriend are there with my son. My son has a childs body with an adult head but he doesn't look like himself. Then suddenly I am standing next to a van with the driver's door open. I see my ex and his girlfriend and I ask them if they want to use the van.
