Moon mai Rahu Ke Dasha

If the dasa (main period) "maha dash" of moon is effected by Rahu "bhukti" (sub-period) the results are very confusing i.e. a person feel that he/she should leave current job & join other job or should change his business etc. etc. If this dasha is effecting 7th house/7th house lord or moon is lord of 7th house than there are problems related to marriage life starts. Hence, during this dasha period one is upset.
