Buddha spoke mainly of discipline related to the Noble Eightfold Path. He also says one must understand Four Noble Truths.
There is no place I've seen Buddha speaking of meditation which doesn't speak of either The Four Noble Truths or Anicca, Dukkha, Anatta.
Whichever form of meditation teaching you follow that doesn't emphasize on these facts actively, isn't Buddhism.
Body is a very complex system. YouTube contains a lot of material on this such as what happens in the body when a virus enters or how many other things live inside us. So what you experience could be one of many million things, if not more. Please don't take this the wrong way. What I suggest is you follow the right meditation, as explained by Buddhas teacher - Dhamma.
Dhamma, the teacher recommended by Buddha himself, is still available and easy to understand, which begs the question of why follow some other teacher?

Give not importance to any of these experiences. They are just conditioning. If you give importance of have prejudice towards any meditative experience, you might end up generating aversion and craving.
What these experiences could be:
When you get such an experience try to see the arising and passing nature of it! This experience, as with any other experience, in essential you your practice of equanimity. Whatever your experience be equanimous - this is the exercise and what you should be doing.
I saw a Dog, Snake and Centipede before sleeping, as soon as I closed my eyes.
People have odd dreams / day dreams. I am not sure what this means. Buddhism does not deach how to interpret dreams.
Like anything else, do not give any importance. Be equanimous.
Also there is a lot more of what the Buddha taught than what is taught in a 10 day course. The Tipitaka is very vast. This contains all which what Buddha taught.
