Just the shore of an entire infinte large ocean. Glad to hear you got your feet wet! I know that feeling too on the come up as well, i say to myself "You know what you did..." lol makes me feel better.
It only gets more intense, way more visuals (man, the visuals), and surrendering to the exp is key. Just let go, if you try to hold to this "reality" then you get some fear and anxiety imo.
Welcome to the nexus!

Lots of good people here.
