Hi Ellenapillak,
For information about rahu-moon cycle one need to see their placements in the chart. Houseplacement, house ruler, nakshatra, sign, and placements in the various subcharts for different areas of life.
But one can also say some general meanings that often turn out true.
Rahu and Moon are enemies, as Rahu is the eclipse making symbol that can cover the moon during eclipse.
The Moon is mind, emotions et.c Rahu can aggreviate the moon in this period. That can make the mind worrying a lot. Often without proper cause. So it is important to make efforts to calm the mind and being objective. So methods like mindfulness, yoga, breath awareness et.c. can be useful during this period that last 1-2 years. As the mind and the breath are closely linked.
Good luck
OM
