Well it's not a regular problem So i doubt any major issue but still... Since past few months i am feeling shaky hands and also some weird feeling all day long.. Sometimes it last whole day and sometimes it doesn't.. And also that lately my dreams seems to be abnormal that i always wake up in between a dream because of some feeling like someone is keep on shouting my name.. And the intensity is such high that i can't sleep again then.. And there's nobody in my house except my mother so i am damned sure that there's nobody calling my name in reality.. Also the fact that i am not scare of living alone because of my working parents . Most of the time my body is vibrating inside and i always feel that i am going to faint anytime.. Other problem that i am facing is muscle weakness and stiffiness, pain in lower back of my head.. So my question is that what could possibly be happening to me ?
