How abt dis..
select dt from
select trunc(sysdate,'mm')+level-1 dt from dual
connect by level < to_char(last_day(trunc(sysdate,'mm')),'dd')+1
)where to_char(dt,'dy') = 'sun';
and a small block
declare
     l_last_day     number;     
     l_next_sunday     date;
     l_first_sunday     date;

     j := to_number(to_char(to_date(l_first_sunday,'dd-mm-yyyy'),'dd'));
     for i in to_number(to_char(to_date(l_first_sunday,'dd-mm-yyyy'),'dd')) .. to_number(to_char(last_day(trunc(sysdate,'mm')),'dd'))
     loop
          j := j+7;
          exit when j > to_number(to_char(last_day(trunc(sysdate,'mm')),'dd'));          
          dbms_output.put_line('value of j : '||j);
          select     to_date(j||'-'||to_char(sysdate,'mm-yyyy'),'dd-mm-yyyy')
          into     l_next_sunday
          from     dual;
