I was in bed asleep.I heard slightly different noises than normal in my room(I have a cat,and birds)I raised my head off my pillow,opened my eyes,and I saw the first entity.He was about 4-4.5 ft.very dark gray,all most a shimmer to his skin.His face was very fat,His eyes very large and beautiful,almost swirling affect to them,he looked at me and said nothing,but I got the impression he wanted me to look over at the rest of my room,Next to him,another entity w/in a foot,I looked at it,it "acknowleged"me as well,and then in the corner of my room,right by the window.I then looked back at the closest,he was looking at me,and we seemed to be talking,telepathically,He assured me that I was safe,and they were there to do no harm,(I have been really sick for a long time with chronic infection,and in and out of the dr and hospital).He tilted his head and looked at me,as he "understood I did not feel well"all most "sympathetic"I will never forget his face,and how kind I felt he was.I was never scared.I looked at him again,confirming my safety,and that they were just going to "watch me"or something,I looked at the other 2 told them all I was "going back to sleep then".The closest one looked at me as if to "approve"and I went back to sleep.When I woke,I was afraid to tell my family,I never have had dreams like this,it was so clear,and vivid,and every detail,I went over in my head again,and again.When I awoke,I searched my body for some sign,and found a "silver dollar size"ring on my stomach,to date,nothing has taken it away.I am profoundly affected by this as I DO NOT BELIEVE IN ALIEN ABDUCTION!!!Ever!Though I have seen many crafts all through my life,beginning at age 5,and having actually been "followed"by a U F O,all accounts witnessed,I never believed that aliens would bother with humans!!!I am confused,ashamed,embarrassed,and very distraught over the whole encounter.Now,questioning my sanity.Please,is there any definitive way to know??I am thinking about renting or buying a geiger counter,because I hear they leave traces of radiation?Maybe hypnosis?A lie detector?anything,so I know I'm not crazy!!The circle all most looks like "ringworm"but has not responded to ANY medications,cortisone,ketoconozole,any anti fungals,covered,uncovered,the only thing it seems to respond to is "zinc oxide"
