please explain to me step by step, how to produce sounds like horse sounds in electric guitar ?

(Why must I asked this question ? it`s because when I was a high schooler one of my friends can make that sound.. Therefore I`m a bit curious about the way to produce it..)

Feed it some hay.

This. Also, just experiment with a lot of feedback/distortion/tremolo/unconventional methods of getting sounds from the guitar (like hitting the back of the guitar, blowing on the strings, anything)
