Night visitor

In Italy, when I was 4 or 5 years old staying at my grandparent's house in the country. One of my aunts took me to bed, tucked me in and turned off the light and closed the door as she left the room. A minute or two later a circle appeared on the wall and enlarged into a vortex. A small humanoid creature came out of the hole and jumped onto my bed. It told me not to be afraid, and we played a game and then I was taken into the vortex and into an Alien ship where I met other children my age, older and younger. "UFOs in the year of the Dragon."
