bump in the night

i have always heard every noise and never felt secure, not when i was a child not as teen and not as adult, married or single mom. so i had to use what i had to get me through each night, as a young child there was nothing i could do except pray that whatever was out there would stay out there.
A few times i sneak my dog into my room but they would not allow that and the punishment was not worth it. but my dog would set outside my window and would run off anything, so that maid me somewhat secure. preteen i had a radio but they always came in and made me turn it off. i used head phones. then i started using a fan--they did not use air in the house-only in their room. but they always came in and turned it off and if i had been asleep it woke me up. i never stopped using it and they never stopped turning it off. when i moved out and living on my own i got a dog but the problem with that is when he barked-what was he barking about? was there something to fear. after marriage and him coming and going at all hours and i had to get sleep for work so i used music and the fan. that way helped when he brought friends over for a party, i could usually sleep through or go back to sleep. when i was divorced with two small children living in apartment building with all kind of noises i found that by having a cat it made noise all night with jumping and knocking stuff over so the fan and cat made it easier to sleep. then when i became stressed when we moved to house in the country there were so many new things that make noises plus my mind was always running remembering the day and what was said and done, then thinking about what i had to do tomorrow ect for day and next day.... so i started leaving the TV on but the problem was i would listen and paying attention to what was on so it just added another thing that kept me up...i learned that playing a Disney movie which was one that i had seen so many times i knew it by heart, so it could be on and i would not "focus" on it but i could let my mind focus on it and that would take my mind off everything else. as the kids left home i am now on my own and for a year or so i did not have any animals in the house so all the bumps i had to question. before i had jokingly said that the house had ghost in the house that made all the noise. lately i have not felt the ghost so i did not know what was making the noise so for my birthday a few months ago i got one small house puppy and went to the humane society and they got me a 1 year old big fluffy cat and 1 kitten. So with the fan, TV and animals i can know sleep with all the bumps in the night. Unless i think about it too much and then i get myself scared and i start all over. everyone thinks i am crazy but hey i am a person that thinks too much and too deeply so i do what works for me.
