Are you talking about random movement having a non-null (aka about 100%)
probability of returning to your starting point (sort of) ?

In 1D (moving along a line), with whatever balanced distribution, it
seems rather obvious.

In 2D (moving in a plane), it's less obvious but you will cross your
previous path at a moment or another.

but once in 3D, you're lost and would quasi-never cross any points from
your previous path.
