In last night Dream I was in a building where it was an escalator..I did see a black cow or bull in the escalaor going up..I made an halt and said to myself..I am not going to use that escalato but soon the cow/bull came Walking toward me I could not understand how he/she could be down staires again, what way did it take..I walked quickly into the escalator and it did stop so I had to use it as an ordinary steps, the cow/bull did walk towards me, I did panic and kicked towards it to go away...I did feel so much fear that I awoke myself from the Dream...
