Good deal, man. Dryer sheets are the shit. They work wonders, you don't even know.

Like many have already suggested, I'd go with the outside method, but it seems as if that's not an option. You should be set with the dryer sheets/fan. You may also wanna block out any vents or openings that may be in your room. Use a shirt or towel or something. You may also want to cover the crack under the door.

But if it was already chill doing the method you did, then fuck it--You're straight.
