It is possible that you are blocking the memories. That is the nature of the unconscious mind. The theory of repressed memories essentially is this: the memories are blocked because they are too painful. You may remember them, at some point in your life, if there comes a time when you are consciously able to deal with them.
It’s certainly odd that your parents would be openly discussing these claims with friends. One would not expect to hear about their own alleged sexual abuse from friends of the family. It would have been informative to know more about the nature of the conversations your parents had with their friends about this alleged abuse.
Unfortunately, there may be no way to know if their claims are accurate. You might consider asking your parents directly. Understandably, you may not want to ask such direct questions, but it might be the only way to know.
Hopefully, this is all a big miscommunication. The friends may have mischaracterized what your parents said. Not everyone’s characterizations are accurate. It is something to consider. I hope this helps. These take care.
