CDC called... Advice requested

As the title says, someone from the CDC called, after having tracked my Reddit account to my phone number (they admitted to hacking into a few accounts, but have sent password-change emails for me to change my passwords on those accounts with advice (given during the call with me) to "make them harder").

They want to set up cameras in the yard so that they can observe the young ice dragons and, in response, they'll help me figure out what's going on with my dreams. They didn't give a reason why they want to do either.

They told me to call back when I decide to give them the all-clear, and then they hung up.

Should I? I mean, they seemed to have shaped-up a lot, but I still remember back when they would just keep killing dragons because of the dangers they seemed to pose. So, if there's anyone here is in the CDC or had recent, proper contact (more than just a phone call) with the CDC, could you explain how much better they've actually gotten since their rough start (as in, how likely it is that they are actually going to just observe the ice dragons)?
