If it is of any interest Bill, my ummm "experiences" were related to periods of extreme stress in one of the participants; in one instance involving the horrific death of another family member.

At the time, I told my wife what thought had happened and within hours we were awakened by someone bearing the news.
I have had these ummm "experiences" on several occasions, always involving very stressful circumstances and always with someone very emotionally close to me.
I think there is are perhaps many "senses", which may have been available on demand in an early stage in our evolution, but which may have been lost or become faint like our sense of smell or hearing.

Sorry about the drift.
