A childhood belief about sleeping

When i was young i used to lay my head on my pillow and listen to the tv in the next room. after a while when i was getting really tired i would start hearing this kind of "ba-boom, ba-boom, ba-boom" and i knew it was a heartbeat. what i diddnt know was tha it was MY heartbeat. i was so sure that there must be a camel living in my pillowcase that i screamed, turned on the light, and threw my pillow out the door. well, think of it from my parents perspective. a little girl screamind and siddenly a huge triangular-green pillow flying towards them. yeah i was a nutcase. after being assured that there were NO camels whatsoever inside my pillow (which was now on the floor) i went back to bed. well sure enough i heard the "ba-boom, ba-boom, ba-boom" again and diciden it was simply that the camel was obviously playing soccer and i decided not to disturb him
