  The phenomenon of interaction between planetary nebulae (PNe) and the
interstellar medium (ISM) is one of the significant issues in the field of
astrophysics. The main objective of this paper is to verify the interaction
process for objects that have been known as interacting PNe (IPNe) in the
literature. This study is based on parallax and proper motion observations
facilitated recently by the early third data release of the Gaia space mission.
Based on the proper nebular central star (CS) motion towards the region of
interaction between the PN and ISM, we were able to verify the interaction
process for a group of 68 PNe and disprove the interaction process for a group
of 33 PNe. The members of both groups were confirmed as genuine PN-ISM
interacting objects in the literature. The members belonging to the 33 PNe
group are false PN-ISM interacting objects that mimic the structure of IPNe.
Moreover, we calculated the physical and kinematic properties of the verified
group and analyzed their galactic population classification using reliable and
precise measurements of the proper motion and parallax of the CS. We find that
41\% and 41\% of this group are associated with galactic thin and thick disks,
respectively, while 18\% are members of thin or thick disks. The kinematical
results show that the galactic thin-disk members have smaller vertical galactic
heights, space velocities, and peculiar velocities than those belonging to the
galactic thick disk.
