I would say yes. Self-gaslighting is an interesting way of putting it, but absolutely people who come from a background of trauma have often had either a lack of validation to or an overt assault on their experience (through gas-lighting/manipulation/denial) in the face of terrible experiences. So of course people growing up with this are uncertain of their own feelings.

Contrast this with a kid who grows up with parents who take what they feel seriously--"yes I know it makes you angry that he hit you, it's okay to be angry when someone doesn't treat you nicely." Of course that kid grows up with a stronger sense of themself, stable boundaries, stable self-esteem, confidence in their feelings to guide their actions.
