  We unveil the relation between the linear Anderson localisation process and
nonlinear modulation instability. Anderson localised modes are formed in
certain temporal intervals due to the random background noise. Such localised
modes seed the formation of solitary waves that will appear during the
modulation instability process at those preferred intervals. Afterwards,
optical-event horizon effects between dispersive waves and solitons produce an
artificial collective acceleration that favours the collision of solitons,
which could eventually lead to a rogue-soliton generation.
