why dont/didn't you just talk to it if its so intent on gaining your attention?

If it actually wanted to harm you it seems pretty clear to me that it would have easily done it the moment you sensed it.

For all you know this dark being could have followed you or been sent there to teach you something or ask for help or even help you.

Looks have the potential to be quite decieving, especially when the one sensing it is reacting in a strong negative way to it.
