This is a slight variation or synonym for Hiller's earlier work, focusing on rich harmonic warmth. Its distinctiveness lies in its evocative, hymn-like melodic construction.
At Henle 4 this is an intermediate piece that expects secure technique and real attention to phrasing. The main demands: chord voicing — bringing out one note inside a handful of others; careful pedaling — clarity depends on the foot as much as the fingers; and a true singing tone, with the melody floating above the accompaniment.
Beyond that, expect rubato that must breathe naturally without losing the pulse.
The main difficulty is achieving a balanced, chordal sound that avoids harshness.

Ein Traum in der Christnacht is rated Henle level 4 of 9 — intermediate repertoire, roughly ABRSM grades 5–6. In the RCM system it corresponds to about level 6.
You should be comfortable at Henle level 4 — meaning you can already play level 3–4 pieces cleanly. Learning it one level early is possible as a stretch piece, but more than that usually leads to months of frustration.
A typical performance of Ein Traum in der Christnacht lasts about 5 minutes.
