Watching a stream of thoughts from the mind?

Watching bodily sensations is simple ,there is **always** a sensation to recognize in the present moment .Same with breathing ,hearing and seeing.Always a reception exists realtime. > For example:- > > In breathing: there is a slow breath ,heavy breath ,refreshing breath. > > In the body:There is comfort ,tightness ,discomfort. But the mind as a sixth sense isn't as easy .It doesn't seem like it always keeps receiving a continuous stream of thoughts to recognize in the present. Is there a meditation practice that can help recognize thoughts continuously ?.Or do thoughts pop out erratically and according to ones interaction with the aggregates?. **Edit** What I mean by thoughts as in ideas coming to the mind.
