Is this your first serious dry spell of inspiration? I know that the classic "writer's block" happens every now and again, which sucks since you really can't do anything about it. You want to write/create so badly, but the desire and passion just isn't there. It's not fun I'm sure.

I've felt that way at times, and as you say, it's weird; You just feel kind of empty somehow. Not fun.

One thing that sometimes helps me is to watch/read some new movies or books to get exposed to new ideas that might spark something. Or even old ones you liked in the past, for that matter.

Sooner or later you'll end up suddenly thinking "Hey, I wanna draw a lion!" or write, or whatever. Sometimes it takes awhile, but if it's something you enjoy, it always pops up again when its ready.

It can be a real pain in the meantime though.
