Rabbi Elchonon Wasserman, a close talmid of the Chafetz Chaim, supposedly was involved with a dybuk. The Artscroll biography of him says he would repeat the story every Purim. See here.
This is also recorded in the book Lev Eliyahu compiled by Rabbi Shalom Shwadron (Sefer Bereishis, pp. 28-31). See here for a translation.
