What Happens when you tell someone in your LD that you're dreaming

Comment below if you've ever experienced a LD where you tell someone or make a conscious realization that you're dreaming "out loud" and something drastic happens. When I become aware I usually just relax and go with it, but if I make a deliberate exclamation of the fact I'm dreaming or question someone else something very bad usually happens and the dream quickly evaporates to me awaking. Anyone else have similar experiences?
