For the bedroom, you can add artificial spider webs placed in the corners of the room. The way to make artificial spider webs is to use tree branches and white wool. Then wrap it around like a cobweb. As for the profit-spider itself, you can make tennis balls painted in black.
In your bedroom, there must be a desk lamp. To make the table lamp look more Halloween, please use black cardboard scissors to resemble a spider glove. Then place it in the lampshade. Later when the lights are turned on, you will see a cobweb in the lampshade. In the end, some of these Halloween bedroom decor ideas are very interesting and worthy of your attention.
