Question: did you buy your trailer new or used? The reason I ask is that if used, the previous owner may have had an electronic sway control installed. These are motion-sensing gyro devices that will activate the trailer brakes when a sway condition is detected.

If you felt like the trailer braes activated, they very well may have. The groaning you heard would have been weight distributing hitch straightening out suddenly in response to the trailer brakes coming on.
If you bought the rig used, the previous owner may have had one of these installed and that info wasn't passed along as part of the resale to you.
If you didn't activate the brakes manually, then something made them come on. If a short breakaway cable caused the pin to pull as the trailer swayed, the brakes would have stayed on after the event. Only other explanation is a short in the umbilical cord that sent voltage to the brakes as the cord flexed during the sway event, but that's pretty unlikely.
Check the trailer when you have a chance, I'm betting you have one of these electronic sway devices installed under the tongue.
