I started hearing weird noises, whispers, screaming people animal and computer noises before falling sleep 
Has this happend  to anyone? It doesn't happen very often for me but  it's not the first time and it is something normal when I am very sad or stressed
The line between awake, REM sleep and stage 1 sleep comes with all kinds of hallucinations. Most people see images, but hearing random sounds isn't all that uncommon.
