Working out the details.

This was all getting a little too weird to be a prank. "Becca, seriously, are you messing with me? You've never done yoga before. How are you doing this?"

Becca thought hard. "Maybe... maybe you're right. I know I've been practicing yoga for years, but you really seemed to think you were a guitarist just now. So this thing makes you think whatever changes it made have always been there. Cool!" She paused. "Still, though, it's weird. I can't seem to hold onto the idea that I don't know yoga. I get it, but as soon as I focus on something else, it's like my mind reverts and I forget. It's really weird."

Julie was starting to get concerned. She quickly reached in and removed the yoga pants. "And now?"

"Whoa, I, uh... what happened?" Becca looked dazed. "Did I know yoga? I can't do yoga! What the hell just happened?"

Julie put her hands on Becca's shoulders. "Think, Becca. Do you remember doing the wheel pose?"

Becca frowned and concentrated. "...yeah. Yeah, I think so. That's so strange, it's like a memory from a different lifetime. Like it was me but not me. This thing is nuts!"

Julie agreed. The more she thought about it, the more she had a vague memory of playing guitar. It was like a dream, though. The details were very hazy. "So it seems that if we know what's happening, with effort we can push back against the cognitive effects of the thing. This is really interesting."

"Told you so!" Becca was wearing that smug grin she got whenever she was right. "So what next?"
