To describe a man acting creepily towards a woman, is there a word that means 害怕 (afraid) but less strong?
I suggest:

心里发毛
feel nervous · be panic-stricken
Example: 他让我感到心里发毛 (he creeps me out)

Basically 心里发毛 describes &quot;you have a dread that you can't put your finger on&quot;

dread : anticipate with great apprehension or fear.

can't put your finger on: not be able to say exactly what is wrong or different about a particular situation
