I have received through the power of thinking!
For weeks I have been nagging my brother that he was the only one who borrowed my USB and for those weeks he vehemently denied borrowing it from me. But I was so sure and very firm in nagging him. However, come Sunday night I visualized my USB, its color, appearance, the specific label I taped on it. I held on to the vision and said, "tomorrow you (my USB) will return to me!" Then I slept peacefully.
True enough when my office mate arrived that day, she handed the USB to me. She thanked me for lending it to her. I immediately called up my brother. Apologized for accusing him.
Since sunday, I was able to download an audiobook on the SECRET UNIVERSAL MIND MEDITATION. It claims to clear the mind of negative thoughts by listening to it while asleep.
