Okay , im scared? Is this a ghost i saw???!? or something else!?!?

I was very ill , in hospital... It was unpleasant , Anyway , one I saw a figure , tall , cloaked , standing in the corner of the room , i was particularly ill that day. I asked my parents if they could see it? They were unable to ,after taking medicine , the figure lowered his hand and said something in an Erie but soothing tone and this is what freaked me out! "now is not your time , ill be seeing you" or something along those lines , and something else which was muffled as he faded away!!! Well was it a ghost or am i just imagining things , My teachers auntie had a similar experience when she died! she told my teacher that there was figure... im terrified
