ok so sometimes I fall asleep with the tv on and my dream happens on what I hear, so if they are talking about cars, in my dream I will be doing something about cars, so anyways I think my dream self can hear things in the real world, so what i did was i recorded myself whispering on my phone saying, you are dreaming! do a reality check!!! I made that my alarm and it is set to go off every 3 hours at night and its not loud enough to wake me up, I think this will work!!!
