The dread of dolls or inanimate, humanlike items is known as pediophobia. It might be the result of a traumatic occurrence or a terrible experience with dolls.
Pediophobia can be addressed in the same way as other phobias are, with treatment and/or medication.
The unreasonable dread of depths is known as bathophobia. It may be incredibly difficult for someone suffering from this illness to simply think about depths, much alone be near them in real life.
