New ceiling fixture

In our bedroom, the light switch controls power to an outlet on the other side of the room. Presently, we have a pole lamp which was fine, but want a ceiling light instead. One option is buying a hanging-type light at Ikea for example, and run the wire up the wall to hang from the ceiling. Ideally, we want all the wires hidden.
Is it possible to use the existing wire going through the ceiling to hang a light fixture in the middle of the room? Is it feasible even, to try this as a DIY project?
In several years that we've owned this home, as a tradesperson and a guy handy on the tools, I've done some minor electrical work, hanging lights from existing electrical boxes, changing light switches, etc. Simple stuff.
This seems a lot more daunting, and I need advice before I even think to attempt it.
Thanks.

Welcome to the forums.

What you want to do is not impossible. You need to pull out (don't unwire) the receptacle that is switched and tells us what you see. How many cables come into that box. How many wires in each cable. What color wires are on the receptacle. Do the same for the switch end.

If one half of the receptacle is switched....tell us what color goes to the top half, the bottom half and which one is switched.

 

What existing wire? What is it feeding now?
