Hey, frosthax1, thanks, you woke me up. Obviously, I'm not a very sophisticated user, so require some pretty simple hand-holding. I managed to wend my way through the smart lock setup and determined the following:
On Body Detection was set to 'No;' I have no Trusted places or devices set up and, heaven forbid, no facial recognition. My Trusted Voice setup is for 'OK Google' anytime but OK Google is not set to unlock the device.
So...I'm thinking this isn't the root cause of my 'awakening' phone.
I really appreciate all you guy's support and willingness to help.
Thanks,
Minuend
