I have experienced the same as Sebatianos explained.
It usually happens when you are just been sleeping and waking up.
Normally you don't dream at this stage so intensely but it can happen.
it is possible you heard your parents talk while still dreaming (much like you can hear an alarmclock going off while you're still dreaming)
usually these dreams occur when an alarmclock goes off and you turn it off in your dream and it continues again and again.
