My Aberrant Mind Sorceress had been making frequent use of her telepathy ability to communicate silently and to keep in touch with allies that went scouting away from the party. Then she opened something she was told not to and ended up with a piece of Nyarlathotep living in her mind. When she later used her telepathy on the Monk, the DM ruled that it allowed the outer god to enter his head as well. Now we had a permanent three-way group chat that neither I nor the Monk could leave, whose moderator frequently posted literal nightmare fuel, and the rest of the party was suddenly very insistent that I only communicate with them verbally from now on.
One time I tried using my telepathy on an enemy. His head exploded. Gnarly was very unhappy about me adding people to the chat without permission and suggested that I not do it again.
