There was another dream I read a couple days ago with

In dreams, sex (and sexual implications) are almost never literally translated. The imagery has to do with communication and connecting intimately with people...

On the surface we see this issue of an accusation. Note that in the dream there isn't even a mention of it having -actually- happened. You've already attributed this to a fear of making the accusation. I'd say that you know the dream better than any interpreter could. But let's take the aspect a step further. The accusation is that there was a mistreatment regarding relating and connecting with you as a child. That's the logical followup from the premise regarding what sex relates to.

--> Were there any times in your youth you felt like your connection/relationship with your mother was tainted or broken? This could be as simple as saying something that changed how you see her to something as distinct as watching her actions and choices in life.
--> How did you address it as a child? How did it affect you then? Does it still effect how you see your mother now?

Taking things a level deeper, now...

Your mother is a projection of you. What things in your mother do you relate to now? Do you, maybe, see those things that changed how you related to her as a child in yourself? How is this effecting you?

And you held your mother off with stuffed animals...

Stuffed animals are innately non-threatening, and often symbolize childhood and innocence. (If you see them a different way, how you see them takes priority to the 'common answer'). Was there some way you coped with problems relating to your mother, as a child? Now, being grown up, you don't have these stuffed animals anymore, but you're subconsciously seeking a way to deal with the schism.

--> What coping techniques are you utilizing? Are there any that you're seeing as ineffective? How can you shift your perspective to make relating to your mother easier?
