  Diversity of interpretations of quantum mechanics is often considered as a
sign of foundational crisis. In this note we proceed towards unification the
relational quantum mechanics of Rovelli, Bohmian mechanics, and many worlds
interpretation on the basis so called Dendrogramic Holographic Theory (DHT).
DHT is based on the representation of observed events by dendrograms (finite
trees) presenting observers subjective image of universe. Dendrograms encode
the relational hierarchy between events, in applications they are generated by
clustering algorithms; an algorithm with the branching index p >1 generate
p-adic trees. The infinite p-adic tree represents the ontic event universe. We
consider an ensemble of observers performing observations on each other and
representing them by p-adic trees. In such observers universe we introduce a
kind of Minkowski space structure, which is statistical by its nature. This
model unites the observer/system discrepancy. Measurements are performed by
observers on observers. Such observers universe is dynamically changing and is
background independent since the space itself is emergent. And within this
model, we unify the aforementioned interpretations.
