I think "to go in above one's head" is an expression meaning "to take too much one can handle". Is that correct?<br/><br/>I think one can use it when one is talking about going into water:<br/><br/><font color="navy">1-I went in the water above my head.</font><br/><br/><font color="navy">2-I went into the water above my head.</font><br/><br/>I think "1" is correct but I am not sure. I am not at all sure about "2".
