Something like counting sheep - but in reverse.
- Count down from 100 to 0
- Imagine each number ( like you are viewing in a calculator display or in any font you like )
- External thoughts may come and go , consistently come back to the last number you have seen.
I usually wander in external thoughts for .5 or 1 sec and come back to the last number. Then, sleep somewhere between 50-30
- For morning time / loud surroundings, use a White noise music. Low volume on a Noise cancellation earphone.
Have privacy concerns, like "they" track my kid, but it's good to find where is my kid now.
