This is an excerpt from the LDOCE.

to become very anxious, upset, or afraid, or make someone very anxious, upset, or afraid :  
People just freaked out when they heard the news.

The whole idea freaked me out. 

I'm curious whether freak out has the meaning of "make somebody angry".

Answer 1

To "freak somebody out" is to startle or upset or scare them. They can get angry as a consequence, but that is not the direct meaning.

You really freaked me out when you told me the tests showed you had cancer. I'm glad it turned out to be a false positive.

You really freaked me out when you lied to me about the test showing I had cancer. Did you think that was funny, you jerk?

Both first sentences use "freaked out" to express consternation. But the consequences are different in each.

Answer 2

The confusion can come by the fact that upset could be synonym with angry in some case. But in this context, upset takes the meaning of distressed.

Freaking out is more expressing some kind of irrational fear or distress, to the point of not acting like one usually do.
