A dream journal would be a very good idea, I think.
It would be very interesting to know whether you manage to record any scraps of actual Russian (or the language that sounds like Russian) from your dreams. Since dreams are you, talking to yourself, it's perfectly possible to know the meaning of foreign or gibberish words, simply because it's you who've endowed them with that meaning in the first place. I would also point out that your answer to eight bits' question about how you know it's Russian is circular: you know you can recognise Russian, mostly from the dreams themselves.
If you didn't manage to recall any of the actual words in a dream journal, I would suggest that the likely explanation would be pseudo-Russian, which you understand because they've come from you in the first place. Or maybe something even more hazy, if all you're left with is the impression of some topics of conversation.
When we're left with hazy memories from dreams, we tend to assume that the dream itself had much more content, and we've only remembered tiny bits. Whilst this can be true (dream-forgetting is an interesting mechanism), it can also be the case that the dream was ill-defined at the time, and we assume, because it fits with our model of waking life, that we've forgotten bits which in reality didn't happen.
If you did manage to record actual Russian words in your dream journal at any point, there are a few explanations. I think everyone's got a tiny smattering of Russian vocabulary, just from being alive - possibly more than one could consciously produce if it were suddenly demanded. So it could be that bits and pieces are inserting themselves, and it's those bits you record. Or, it could be that perhaps these dreams have sensitised you somewhat to pick up on any Russian things you come across in daily life, which would then be incorporated (or perhaps your dreams even move you to go out and start finding Russian speech to listen to).
Beyond that, there are of course paranormal explanations such as past lives, telepapthy, precognition, etc. - but it's going to be extremely difficult to rule out the naturalistic explanations in this case.
Anyway, if you keep a dream journal, try to record any examples of the language, topics and content of conversation, geography, details, narrative, etc. if it's interesting to you to see if it matches with reality (maybe even with a particular point in history?); but it's also interesting to record feelings, meanings, your own interpretations and even fantasies about what happened next, to see what the dream might mean to you.
