Welcome to the forum!!
You will find a wealth of info on the paranormal in this forum. When strange things happen it is always wise to trust your gut but also you must be prepared to "de-bunk" experiences. It sounds like you are in fact trusting your gut AND you have a healthy "de-bunking' spirit.
Whatever is happening I hope that our community can help you in the process of figuring out what is going on.
Light & Love to you
