.. Opening the door in the Stag dream

Maybe you should fill the missing pieces.

Like, put the door mat on top of the rectangle.

It needs a lock (to put the key in) and a knob.

You can find the knob in the cupboard. The diary on the left has a lock. Put them both into the door.

Open the door with the key.

It was drawn. ( The key is under the mat. )
