does hanging up posters on a a ceiling really make mold?

i want to make a jonas ceiling, but my mom said i cant because she said because of the heating on the ceiling the back of my posters will get mold on them…(theres no mold on my ceilings though…) so will posters on my ceiling really make mold?

no, mold comes from moisture(water) built up….not true whatsoever!
