Actually, it is not your gandhabba doing that. Your gandhabba is inside your body, and is essentially your “being”. The physical body is just a temporary residence for the gandhabba, the mental body. There are many posts on this but here are a couple: “Gandhabba (Manomaya Kaya)- Introduction” and “Our Mental Body – Gandhabba“.
I would encourage you to use the “Search” button at top right to find more posts, and also to read the links given in the above posts.
There are many unseen beings in our world. There is evidence that there are such “good beings” and “bad beings”. See:
“What Does Buddha Dhamma Say about Creator, Satan, Angels, and Demons?”
Both these types can try to stop one from following Buddha Dhamma, as discussed in the above post. If you can give some details of your experience (if you are comfortable in doing that), I and others may be able to provide some input.
It is possible that more readers have had similar experiences. Before starting the discussion forum, I got several emails describing their experiences.
