What do I do about my nose clicking?

[Artqueen001]

So sometimes  (and it doesn't happen to often) when I lay my head side ways on my pillow I hear a soft clicking noise coming from my nose after I breath out. It doesn't have an odor nor does it hurt but I feel the soft vibration on the upper part of my mouth. It doesn't matter if I breath slowly or fast, through my mouth or nose the clicking continues. It doesn't click however when I sit up or even lay on my back. Is this a dental problem or something else.
