I have a weird theory about that. I hear one ring, one message ding, the doorbell, or even my name while I am sleeping. Finally, I associated it with a pause in breathing. Either my subconscious or an external entity is waking me up to prevent sleep apnea death.
Think about that.
“Finally, I associated it with a pause in breathing. “
I have had two episodes of sleep paralysis in the last several years. Both times I was sleeping on my back. The only times I was on my back.
The first time I thought maybe I was dreaming. The second time I knew it was real.
Ditto, one ring and it is my cellphone ring tone.
