DEATH in the game makes no sense: (Part 2): "zzz" unconscious characters - How do you wake them up?

My character (the healer) went down.  And she passed 3 death saving through and was stabilized but unconscious.  

The other characters could not wake up her. I tried for 3 rounds in a row.

Then suddenly she had 1 hit point and got up.

Why could I know wake her up on my own. I used the medicine skill to stabilize her. But she would not wake up.

Why is there no "WAKE UP CHARACTER" option?
