  EPIC 204278916 has been serendipitously discovered from its K2 light curve
which displays irregular dimmings of up to 65% for ~25 consecutive days out of
78.8 days of observations. For the remaining duration of the observations, the
variability is highly periodic and attributed to stellar rotation. The star is
a young, low-mass (M-type) pre-main-sequence star with clear evidence of a
resolved tilted disk from ALMA observations. We examine the K2 light curve in
detail and hypothesise that the irregular dimmings are caused by either a
warped inner-disk edge or transiting cometary-like objects in either circular
or eccentric orbits. The explanations discussed here are particularly relevant
for other recently discovered young objects with similar absorption dips.
