Well, possibly, depending on who you feel is inside, it might be that you associate that person with the condition the actual body in the dream is in.

So for example, if you saw a sick person in bed and it felt like your brother you might feel your brother is (getting) sick one way or the other. Or if they're in bed you might feel like they need a rest, or you want to watch over them. There are many many options so its hard to say..

Dreams are very abstract though, looking for a meaning can be quite hard..but yeah, I'd rather listen to the feeling than what I see in dreams, when it comes down to identifying people.

What do you think it means yourself? Your own intuition is the best tool you have here ^_~
