Antonyms for "auto suggestions" are quite scarce due to the nature of the term. Auto suggestions refer to the practice of influencing one's thoughts and behaviors through repeated affirmations or self-talk. The opposite of auto suggestions would be negative self-talk, where one continually reinforces negative beliefs and behaviors. However, this is not necessarily an antonym, but rather the absence or reversal of the practice of auto suggestions. Alternatively, one could argue that the antonym of auto suggestions is external suggestion or external influence, wherein one is subject to the influence of others rather than actively shaping their own thoughts and behaviors.
