  We explore a model of the early universe in which the inflationary epoch is
preceded by a cosmic bounce, and argue that this scenario provides a common
origin to several of the anomalous features that have been observed at large
angular scales in the cosmic microwave background (CMB). More concretely, we
show that a power suppression, a dipolar asymmetry, and a preference for
odd-parity correlations, with amplitude and scale dependence in consonance with
observations, are expected from this scenario. The model also alleviates the
tension in the lensing amplitude. These signals originate from the indirect
effect that non-Gaussian correlations between CMB modes and super-horizon
wavelengths induce in the power spectrum. We do not restrict to any specific
theory, but rather derive features common to a family bouncing models.
