Hi Aija, welcome to the forum
To respond to your question, can you share more about in what context is your body changing? What kind of 'weird' experiences are you getting from it? Is it something you've referenced with doctors already - in case there is something concerning your health? And what are the experiences - as emotions - that you are experimenting on it?
So as with any other topic, expanding on the writing will assist in you grounding the question and us getting more background to give a perspective if possible.
