3 ciekawe wyjaśnienia z http://www.twinpeaks.org/

There are three theories, possibly related:

1) The hand shakes are a precursor to the appearance of BOB
at the end of the episode (spotlight in Glastonberry Grove,
appearance of a hand, followed by BOB himself, saying "I'm
out!"). BOB's hand also shakes when the one-armed man and
the LMFAP demand their garmonbozia from him near the end of
FWWM.

2) Some relation to Teresa Banks' and Laura's left arms
going numb in FWWM, although the episode 27 hand shakes are
*right* hands. It would also appear that FWWM arm numbness
is related to the "owl" ring, which is not shown in the
series.

3) Cafeine withdrawal:

Were any of you paying attention? I'll set it to you
direct from the show.

1. The show equates engine oil with coffee.

2. There was something odd about the river - don't
recall who says it.

3. All people who get the hand shakes were drinking
coffee during or prior to the experience.

In other words - coffee is our own personal engine oil.
We need it to keep from rattling. And when we get
"low quality coffee" we get the jitters, shakes and
rattles.
