EXAMPLES:

I have manifested physical items. The first time this happened was quite by accident and was very startling. I was breaking down boxes at my previous job in a restaurant. I didn't have my pocket knife with me, and the boxes were blocking the entire kitchen area while the freezer was being stocked. As I struggled with my hands, I thought to myself how a blade would be useful. At that exact moment, I heard something hit the stainless steel table I was standing over. I looked down to see a used metal cutting sawzall blade that basically just fell from the aether.

I have affected the elements. This past summer, I was sitting at the computer when a sudden deluge hit. Then I realized that I had left an item outside in the back yard by accident. I went to the back door and the rain was so heavy that I could barely see. An umbrella would not have been much good, so I decided I would casually walk outside to retrieve the item and tolerate how wet I might get. I opened the door and my arm did not get wet. Without hesitation, I went out through the door and started walking at a normal pace to the back of the yard. Not one drop of water had fallen upon me. The rain stayed about an inch in front of my face the entire length of the yard. When I stopped walking, the line of torrential rain continued at the same pace as I watched on in utter amazement.
