Scroll down to Make one's hair stand on end.
All the best.
What is the meaning of "raise the hairs on the back of your neck"? I have been searching the meaning from dictionary but to no avail.
Or if you don't feel like it, here's the expression, straight from the website itself (I hope that's ok to paste material here if the source is mentioned):
Make one's hair stand on end -terrify one
A reference to the effect of extreme terror on the hair of the arms, head, etc. as noted for example in Job: 'Fear came upon me, and trembling ... the hair of my flesh stood up' (4: 14-5). Hence hair-raising and its slang abbreviation hairy (dangerous, risky).
