A cup of yogurt being a phone

Some three nights ago I had one of the weirdest dreams ever. Here goes. I'm in a kitchen and hear a phone ring, but the sound is coming from inside a refrigerator. I open it and look inside only to notice that what sounds like a phone is actually a cup of yogurt. I pick it up, then realize that the cup in my hand is indeed a legitimate phone, and somehow "know" that in order to answer the call I need to partially remove a lid from the top of it. Afterwards I have a regular conversation with my friend by talking to a half-open cup full of yogurt and hearing replies coming from inside of it.
