I think this happens more now that everyong is on GPS supported FMS navigation. We were on airways from KJFK to KIAD.
I had a similar experience on a CRJ into LAX a few years back, although not as extreme as your turbulence. What seemed to me (as SLF) to be a severe situation was probably no more than 15 degrees of roll to the right, followed by an immediate correction. It certainly woke me up that morning!
Whether wake turbulence caused it is something I don't know. It occured north of KLAX over the mountains, perhaps that location may be why there was turbulence, but I'd imagine we were too high for terrain to have been a factor.
Still, it's a story to tell over a few drinks
