Light bulb?

[Sire]

I'm stuck looking for a light bulb, I assume, in the room with the ghost on the chair. She's blocking a door, which seems to be the only way to proceed, and there's a lamp next to her but no bulb in it. I have no clue where one is of if that's even what I have to do but it seems like the next logical progression. I just made it into the corridor and pushed the bookcase to plug that very lamp it. Kinda at a loss.

I was stuck here exactly too, the moment you enter the corridor from the "ghost sitting on the chair" room. turn to the right and keep walking, there should be a light switch on the wall that you have to turn on .

The light bulb is in the corridor in a box on the ground, somewhere next too the bookcase you pushed away.
