No idea! I remember the tables being eating tables, there were people around us... but there was some type of instructor there too-- so cooking class is my best guess lol. Dreams are the result of your short term memories moving through your brain to be stored in long term memory so I have no idea what made me dream about that setting.
I went to school for psychology with a concentration in neuropsychology and took a sleep and dreams class... the professor taught us how to lucid dream... meaning the ability to know you're dreaming and be able to manipulate your dream without waking up. It's difficult, I did it once... it would be fun to be able to do it in a dream like that one

I definitely would not mind a repeat. haha.
