Trees and Dreams is just a short world quest available in the Sumeru region.
Your objective is to go to the designated location after talking to Araja.
Here’s a walkthrough and guide of Trees and Dreams in Genshin Impact.
How to reach the designated location
You will be able to see the designated location on your map but you can’t access it directly from the marker.
Instead, use the Statue of the Seven in Vanarana.
From the Statue, go north towards the location shown below, marked by the player location / custom pin.
You should see a tunnel / cave entrance.
Go all the way in and you’ll see the huge mystic plant.
The quest ends here.
You can exchange Dendro sigils for levels and you’ll be able to claim rewards for each level.
This is similar to the one at Grand Narukami Shrine or Dragonspine.
