Earth quick

Yesterday was 1 hell of a scary night for me, I was at home all alone the whole night so decided to watch the haunted anime that downloaded long time ago. While watching my room light was turn off and half way through the movie, i felt that my chair is shaking left and right and i thought of something but after a while the shake stop so I didn't bother to care about it and when my parents back at mid-night, they ask me did I felt the minor earth quick shake, then i realize that it was an earth quick and not just my feeling error.
