Well the way I remember dreams is to write down notes each time a REM cycle ends (never anything detailed it makes you feel really tired in the morning trust me ) So when I wake up in the morning I am greeted with several entrys I run over them and reinforce them in my memory then that night I go over them again and write them into a seperate book (much more detailed and less messy ) this sort of prepares me for the night and points out dream signs I may have missed in the morning. Well this is how I do it anyway, good luck in improving your recall.
P.S: A glass of apple juice before bed and/or WBTB is extremley helpful in increasing vividness of dreams which aids in recall .
