I have been in nursing for over 20 years and boy do i have a lot.but to just get started, this incident occurred less than 48 hours ago.i am at work,night shift,and around 0200 in the morning a patient puts on call light requesting a clean diaper change.i was alone at the time and cna on break so i obliged. As i was finishing the request ,i went into patient bathroom to wash my hands.i saw no need to turn on light for enough was coming from patient overbed light.i proceeded to face basin and turned on water and instantly i felt it.a presence standing in the bathroom behind me and the most strangest thing occurred. Never in all encounters had this happened. The presence touched my left butt cheek. It shocked my breath away.i turned to look and became so frightened that i dashed out the room.walking back to the nurses station my mind was debating,did this just happened to me?as i was washing my hands the thought entered my mind,the presence had to be male to touch me of all places my butt.i didn't mention incident until next night with another worker and instantly he said"room 17 does have activity for the patient by the window in the room call them demons".he stated that the patient says there os a.demon in the bathroom and he sees it quite often.well that morning i felt it and i will never forget it.true story.
