strange voltage measurements

I'm replacing a daisy chained outlet, and I used my meter to double check that the power is indeed off.

I'm measuring 1V and 0V AC on the feed to the outlet and the daisy chain from the outlet, respectively. So thats fine. But when I measure voltage across the hot side from the feed and the neutral from the daisy chain, or vice versa, I measure about 18V. Is this just because I'm probing a floating wire in each instance, and I'm picking up stray voltage from elsewhere, which screws up my meter?

You are using a digital meter. The phenomenon is called phantom voltage. If you apply a load to the circuit it will likely go to zero volts.
