cold feet

i have got somthing to share which i had last night i was with my friends at one of my friends house (only grls) we were chatting drinking suddenly i just told them lets pray 4 our work and thanks god then we held each others hands and started praying after few mins we felt calm and relaxed ther was a long silence in the room then after that we started playing quizs i realised that after prayer i started getting cold feet and it became so bad later that they had to switch off the fan except me everybody in the house was feeling hot i was litrally shivering inside i really thank jesus that i rode home safely i kept praying whole way long and then when i reached home i was so much feeling good i cant tell you but i really dont know what happend there after prayer with the cold feet and all
