A Soft Tap on the Cardboard

I... I blinked, and the dim room suddenly felt quite real. My feet were planted softly on the carpet, leaning right against a large blue shipping box behind me. I took a hesitant breath, slowly lifting my right gloved hand. It moved, just like that. Carefully, I reached out and tapped the stiff cardboard beside me with one finger. A faint hollow thud sounded back into the quiet air. I froze for a second, catching my breath, but nothing jumped out. I'm truly able to move on my own.
