Triangular object with multi-colored lights hovering at treelines

Myself, My brother, and my cousin were sleeping.  Loud jetlike-whistling noise awoke myself..strange because I never had heard a jet before in Raymond NH. Ran outside through front door and observed large well-lit triangular object with multi-colored(green, white, blue, orange, red)flashing lights on bottom hovering just over large pine tree in front of house. Note: No street lights in community where I once lived. I started screaming to my brother and cousin to come out see the object hovering above me. I ran into the house screaming in excitement and then ran back out..object was gone(no sign of its departure,no more sound).  I then called my parents who were in Boston at the time to tell them what I had witnessed..didn't call local authorities because they wouldn't believe me anyway. My brother and cousin heard and were awakened the noise but didn't see the object.
Date of incident is approximate.  PD
