toy car was moving by itself as though an invisible hand guided it

Paranormal and psychic happenings my friend had just lost his father, it was Xmas and he bought my son a huge truck we were in the living room when the curtain at the door was pulled back and held by invisible hands and the big toy truck drove itself through bumping into our legs. The kids jumped up screaming. My friend said his father would often do this with his cars when alive. The photograph of his parents on the mantlepiece began emanating a beautiful smell of roses.
