I have one.

Nearly 19 years ago, when my third son was a baby of less than a year, one night I woke up with a strong sense that I should go check on him. So I did, getting up and walking down the hall to his bedroom.

His sheet was wrapped around his neck and his head was totally covered. I disentangled him, saw that he was fine, and went back to bed.

I had never had that feeling, that in the middle of the night I should wake and check on a child, before, nor have I had it since.

I do have a cousin who lost a baby son, over 40 years ago, when a Venetian blind cord got wrapped around his neck while he slept in a crib.... So maybe somewhere my senses are sharpened to that danger.
