Runanubanda means memory on a physical level (scale)… It can come from certain relationships, touches, intimate encounters… The body has the ability to remember particular touches, both with person and object. We have to deal with different situations in our daily lives and as a result, we receive different types of energy from a particular environment. People, the atmosphere, the situation, body can remember all these things, which then can be reflected in our physics. For yogi, this gets disturbing because the sensitivity here is quite high. They often use water, shower as the simplest method of cleansing. There are deeper cleansing procedures like smoke, strong wind, river.
