First what is this "Stream" we read so much of?
Cannot do beter than quote accesstoinsight.org quoting in turn Buddha;
SN 55,5
"Very good, Sariputta! Very good! This noble eightfold path — right view, right resolve, right speech, right action, right livelihood, right effort, right mindfulness, right concentration — is the stream."

And again latter;
— SN 44.8

The coming-together of these factors is called the stream because it leads inevitably to two things, just as the current of a tributary will lead inevitably to a major river and then to the sea. In the immediate present, the stream leads directly to the arising of the Dhamma eye, the vision that actually constitutes this first awakening. Over time, the stream ensures that — in no more than seven lifetimes — one will be totally Unbound.

So it's definitely not beginner stuff,and yes it's indicates a level of attainment
