Mystery of dreams

Hotel’s beds are very public usage. I think anybody sleeps in a hotel’s bed would deposit a part of his body and soul. Also, exchanges some of what was deposited before. So, it’s like communication station between souls. How that would happen? Beside dermatology diseases with maybe transmitted, dreams reflect major part of our experience. I’m really surprised by the traffic of dreams I have every night. Either my soul travels to every place I miss, or souls slept before in this bed came to visit me every night.
