Calling All Brain Studiers

I'm starting to get a little worried. I've talked to a few other people about something I've been experiencing here, and no one else has experienced it, which worries me, despite my enjoyment of feeling unique. I frequently doze off while traveling on trains, buses and maxi taxis - not enough to be considered asleep, but enough to do the head-jerk thing every few seconds. When this happens, every conversation I hear is in English, even the conversations of my Romanian or Hungarian compartment-mates. As I start to doze off, the foreign language conversation will morph into English, but an unintelligible English. An example: Person 1 "The cat's bread went for hair but did it go under something yesterday?" Person 2 "Well I don't swim and there people break into holes and turkeys. Do ladders make songs with sidewalks taking pictures." and so on. It's very confusing. So confusing, and a bit startling, that I'll snap out of it and try to figure out what they're talking about. But, the moment I start paying attention and open my eyes, poof! Back to Romanian or Hungarian. The conversation's too hard to follow, so I drift back into doze mode and the weird English returns. "Becky's car split but your mom's drinking the lamps. They said wait without holding a note and I can buy the whole blue for reason." Stuff like that. Nothing that makes sense. I think it might be similar to how I saw people I knew in the faces of strangers when I first arrived. English is so imprinted on my brain that it takes the first opportunity to turn everything into something somewhat computable. Maybe my brain misses English, though I do hear it fairly regularly. Maybe it can't handle learning a foreign language. I'm jealous of all those volunteers gushing about the dreams they're now having in Romanian or Hungarian, or those who are speaking it in their sleep. I can't even hear Romanian when I'm asleep. What's wrong with my brain?
