  In this work, we investigate how single-sided and eternal black holes in AdS
can host an enormous number of semiclassical excitations in their interior,
which is seemingly not reflected in the Bekenstein Hawking entropy. In addition
to the paradox in the entropy, we argue that the treatment of such excitations
using effective field theory also violates black holes' expected spectral
properties. We propose that these mysteries are resolved because apparently
orthogonal semiclassical bulk excitations have small inner products between
them; and consequently, a vast number of semiclassical excitations can be
constructed using the Hilbert space which describes black hole's interior. We
show that there is no paradox in the dual CFT description and comment upon the
initial bulk state, which leads to the paradox. Further, we demonstrate our
proposed resolution in the context of small $N$ toy matrix models, where we
model the construction of these large number of excitations. We conclude by
discussing why this resolution is special to black holes.
