small orb humming and hovering above me and a friend in hammocks briefly before gliding off

single orb like object humming and hovering above myself and a friend whilst we were camping in the woods in hammocks.
Orb hummed as it came close to us and briefly stopped above us, then seemed to quickly dart off as we became aware of its presence.
Could also hear voices in the woods that night, not sure if it was other people or related to incident.
Not sure on the time or how long the incident lasted. Felt like a short amount of time but then I recall when checking the time more time had passed than I thought had.
