Yes. You've seen lots of noses, eyes, hair colours, face shapes etc. in your life, and your mind is capable of reassembling them through imagination, or through dreaming. You dream of faces that you have never seen before, but what makes you think they aren't composed of parts that you
have seen before? Or of parts to which you apply concepts such as size. It's possible to imagine a real nose as being bigger than it is, so it's possible to dream of incredibly big noses.
I used to dream that my sister had green skin. There's nothing very mysterious about this... I'd seen my sister before, and I'd seen the colour green, and during sleep my memories of my sister and of the colour green were activated simultaneously - or something like that.
