I’d like to make sure I understand the difference between the phrases correctly.
1. fall asleep = start sleeping when you do not intend to, especially not in bed.
The Japanese are said to fall asleep as soon as they get a seat in the underground.
Most men fall asleep while watching TV.
2. go to sleep = start sleeping when you intend to; often used when it’s difficult to do.
I went to bed at midnight, but couldn’t go to sleep till four.
Many women complain it takes them long to go to sleep. – Would fall asleep be wrong here?
3. go into sleep = go to sleep??
Fergus had gone back into a deep sleep.
Some additional comment would be appreciated.
Thanks for your help.
