Parenting Advice Needed!

I have drama. Or maybe it's nothing. You guys tell me what you think. 

Bug was sitting with me and said, "You know what, Mommy? I had the weirdest dream last night. I dreamed that a man was talking to me, but I couldn't understand what he was saying, like he was speaking Spanish or something. And then he made a face like he wanted to kiss me and I shook my head no, but then he kissed my stomach, and then my privates! Isn't that gross?" 

ohmigod ohmigod ohmigod... 

"Um, yeah, that is gross. Did you know the man in your dream?"

"Not really. He looked kinda like Dara's dad."

That perked The Agent up. "Who's Dara? Why do you know what her dad looks like?"

Bug rolled her eyes. "Dara is in my class. Her Dad volunteers sometimes. Everyone is supposed to volunteer.... how come you never volunteer, Daddy?"

That shut The Agent up.

When I put the kids to bed that night, I asked Bug about the dream. "Has anything ever happened like that in real life?"

"Oh, no! That would be so gross!" 

"Yes, it would. But you make sure you tell Mommy right away if anyone tries to do that, OK? You come to Mommy right away and Mommy will take care of you. OK?" 

"Sure." Bug was already losing interest. "But... there is one boy who's already done that."

What???? 

"His name is Jason," Bug continued. "He's not in my class, I think he's in second grade. We were playing Mommy and Daddy and he grabbed my privates." 

"And what did you do?"

"I ran and told Miss Amy and Jason got in trouble."

"Listen to me," I said. "I do not want you to play with Jason anymore. He is not being nice to you. If he or anyone else touches you again, make sure you tell the teacher, and then tell me. OK?

"OK." And that was the end of it. I was rather proud of myself for handling it as well as I did, truth be told.

The Agent was waiting when I came back downstairs. "Did you talk to her?" 

I told him what happened, but that wasn't enough for The Agent.  "That's all? How did he touch her? How did he get in trouble? Why weren't we notified?" 

I didn't know the answer to any of those questions, and told him as much. 

"Don't you care enough to ask?" 

Oh, that fired me up! I came very close to freaking out on him right there. But I made a goal to yell less, so I just sighed and said, "Well, if you care so much, maybe you can talk to her." 

The Agent said, "A little girl doesn't want to have a talk like that with her father." 

Ugh. Whatever. That's the same excuse he uses when I want him to help the kids at bathtime. "She needs to learn modesty," he always says. Yeah, so what's your excuse with BK? 

Anyway, The Agent said I needed to ask 100 more questions, and I said that anyone would close up if  you keep asking them questions. 

So we dropped it. But what do you think? Is this just something that kids go through? If I need to address this further, how do I go about doing it? HELP!
