Pulsating light orbs resembling jellyfish movement

Pulsating light orbs observed for several minutes in clear night sky. Northeastern sky, no higher than the treeline.. orbs were lit up & rapidly changing directions- going up, down, left, right, etc. VERY FAST! Jellyfish-like, Pulsating movements, and seeming to "scan" the ground area below them. We observed while outside on a very cold night, and there were two of them interacting with each other and with the environment. Almost looked like a performance. VERY cold night, so observation was no longer than 10 minutes. I have seen these many times before in this same area, but wasn't aware of database to report until now, so I will be reporting again if/when they return.
