Collecting All A Child's Dream Chests: My First-Person Journey Through Honkai: Star Rail's Darkest Dream

Penacony has always been the dream destination for every soul in the cosmos, a place where people would save an entire lifetime just to set foot in its opulent resort. I finally arrived in 2026, but nothing could have prepared me for the truth lurking beneath the gilded surface. Dreamwalking in Penacony is supposed to be pure bliss, yet when I stumbled into A Child's Dream, the air turned cold. A child's crying echoed through warped hallways, and the scenery twisted into something deeply unsettling. Once I pushed past the Trailblaze mission, the oppressive terror lifted slightly, but the area remained a disorienting maze. That's when I decided to map out every single treasure hidden in this creepy corner of Honkai: Star Rail. I'm sharing my personal journey to help you navigate the dizzying 3D rooms and snag all 19 chests, the Warp Trotter, and the two Lordly Trashcans without losing your sanity.

Before diving into the mind-bending 3D spaces, I swept through the accessible sections of A Child's Dream and grabbed the four easy chests, punched the Warp Trotter, and dealt with one of the Lordly Trashcans. These were straightforward and gave me a quick boost, but I knew the real challenge was ahead. The remaining riches were trapped inside two dream-walking chambers where gravity seems optional and walls become floors at a whim.

The First 3D Dreamwalking Room

I stepped through the portal and had to pause. The room spun lazily around me, stairs leading sideways and ceilings acting like solid ground. After a few deep breaths, I oriented myself and immediately spotted the first chest by the second entrance. Claiming it was a small victory that steadied my nerves. The second chest, however, demanded more work. I spotted a Bubble Charge dispenser nearby and grabbed one. Activating Bubble Bridge A, a glowing path materialized, connecting our starting side to Side 2. Crossing it felt like walking on a luminescent rainbow over an abyss of forgotten nightmares. On the opposite platform, the second chest waited, and I opened it with a satisfying click.

Even in this relatively simple room, I glimpsed a Lordly Trashcan and the Warp Trotter scurrying around, but I dealt with them later after understanding the bubbling mechanics. That first taste of the labyrinth prepared me for what came next, but honestly, nothing could have fully prepared me.

The Second Nightmarish 3D Labyrinth

The second Dreamwalking room was a monstrous tangle of rotating perspectives. I stood at the entry point—marked by a green circle in my memory—and felt the weight of the challenge. Below me, stairs spiraled into nothingness, and floating platforms drifted just out of reach. I followed a meticulously planned route that I now etch into every Trailblazer's guide.

I began by descending the stairs from the entrance to snatch Treasure Chest 1. Right next to it was a Bubble Charge station, so I grabbed a charge and activated Bubble Bridge A, which shuttled me to Side 2, where I scooped up Chest 2 without breaking stride. Continuing onward from Side 2, I hit Bridge B and strode onto Side 3. There, Chests 3 and 4 sat close together like a generous gift. I scooped them up, feeling a surge of confidence.

That confidence was quickly tempered when I realized I had to backtrack. I retraced my steps over Bridge B and then A to return to Side 1. After refreshing my Bubble Charge at the station, I dashed across the main bridge and claimed Chest 5. Pushing forward, Bridge C led me back to Side 2, but to a different segment where Treasure 6 was hidden.

The room began to feel like a living puzzle box. I returned to Side 1 once more, refreshed my Bubble Charge again, and then climbed the stairs to open Chest 7. Those stairs seemed to exist in four dimensions—what felt like up was sometimes forward. Shaking off the disorientation, I descended from Chest 7 and activated Bridge D. On Side 4, I looted Chest 8 and kept walking until Bridge E materialized.

This is where things got feisty. I arrived on Side 3, but it wasn't a peaceful return—a Lordly Trashcan guarding Chest 9 challenged me. The fight was chaotic, with the Trashcan bouncing around and spewing trash talk, but I battered it into submission and claimed the chest.

After the encounter, I continued to Bridge F and landed on Side 5. A quick Bubble Charge refresh later, I scooped up Chest 10. Then I hopped onto Bridge G, which carried me to the other half of Side 4. From there, Bridge H whisked me back to a different segment of Side 1. It was eerie, like walking on the underside of a familiar world. Here, I collected Chests 11 and 12, feeling a profound sense of accomplishment.

But I wasn't done. I retraced the sequence of bridges—H, G, F, E—making sure to refresh my Bubble Charge on Side 5 before crossing. Once back on the main part of Side 4, I strode down to the hall's end and activated Bridge I. Chest 13 shone like a beacon. With that final prize in hand, I noticed a faint shimmer on the wall and slipped into a secret room (the blue circle in my mental map), where one more A Child's Dream chest rested. Grabbing it felt like solving a rubik's cube blindfolded.

Final Thoughts on the Collection

By the time I emerged from these hallucinatory chambers, I had claimed every collectible the area had to offer. The first 3D room handed me two chests with relative ease, but the second required a monk's patience. These 15 chests from the 3D rooms, plus the four easy ones and the Warp Trotter, made the entire set. The two Lordly Trashcans, one in each major room, provided comedic relief and a few stellar materials.

If you're venturing into A Child's Dream in 2026, I recommend tackling this during daylight for your mental peace. Follow my route step by step, keep a notepad for bridge sequences if needed, and don't forget to refresh those Bubble Charges. Penacony's beauty hides teeth, but with the right map, you can strip it of every treasure and walk away richer—and slightly less haunted.
