Such a bias could distort the reality of the matter. Is it not just as possible that Jesus passed these material objects because He had more substance than the door and walls rather than less substance. The angels are not less real because they are spiritual, but more real, more solid, and of a greater existence than the physical. Now the spiritual dimension is just as real as our physical world. There is a whole universe that exists outside of our perception.
Intelligent beings inhabit both the physical and the spiritual dimensions.
God Himself is here waiting our response to His presence. This eternal world will come alive to us the moment we begin to reckon upon its reality. There exists a parallel universe. This spiritual universe exists alongside ours. It occupies the same space as our universe, but most likely at a higher frequency or vibratory level than our own universe.
