so basically you talk to yourself? Well, yes I do that as well. But I usually don't do it if I have frequent communication with others. It mostly is a sign of isolation - at least for me.
How about you? meeting often with people? (often here means long time meetings and being around people all day with little conversation here and there).
It might be a withdrawal symptom. Or it might me simply your brain telling you that it wants more socio-emotional stimuli and to share and get feedback.
Why not document this behaviour here in order to see whether you keep it for longer and especially WHEN. If conditions change, behaviour might change as well.
But don't be too worried. Sometimes we simply ARE weird ;D
