I have been told I'm an empath, so I have started to focus on the energies around me, it was all going great until recent times I have been walking at night and I get a really bad feeling as if something is there watching me than the street light will blow, this has happened more times than I care to count, at first I figured it was tormenting me because the fear that came with it but I got curious wanted to see what it wanted, thing is I didn't get a reply, but in the last few days I have had the feeling outside and inside my house. So curiosity and personal space issues have got me wanting to communicate with this thing again. Though I now recall this feeling over the years but only when I have walked very far from my house and late at night. I can feel its presence, its mood, I can almost see its face, far from human, standing around 8 feet tall.
I know everyone may think me mad for not wanting to try to be rid of it, but I am after advice on how to talk to it I need to ask it a few questions, I didn't summon it, but the more I think about it the longer I remember it being with me.
As strange as it sounds I don't think it wants to hurt me though I don't think I could care less it looks at me and I feel as if it thinks it is better than me it looks down at me as if I were a lower species, but it has taken an interest in me for some reason and I'm determined to find out what.
I figure this thing also knows more about my powers than I do, now I know this will sound really strange but its with me now and this sounds like a paradox but I swear it has a golden cows head, its body is hidden to me but the head is definitely looking at me.
NewbiePsichic seems to sum up your answer very well, so I would go with his/her suggestions.
