Yes, I've had that feeling before. But I doubt anyone living is "visiting" you.
In my opinion, we are surrounded by energy. Of the Earth, of the plants, the air we breath, everything. And within that energy there is a life spark, an awareness. And all things that we perceive has a life spark.
As we become more aware of our selves, develop our own sense of what "magic" is, become more connected to all things around us, we also become aware of their individuality. Their essence.
I would suggest that what you are experiencing is an awareness of the energy and those life sparks that has always been there. Nothing to worry about. And if it bothers you, simply acknowledge it and block it by grounding and shielding.
