I dream about aikido a lot. I tend to dream the most right before testing, during and after seminars and after an intense night of training. To me it is just more practice. And sometimes I'll be having a more usual dream and some aikido will happen in the middle of it
Just yesterday morning I woke up from an aikido dream and the last thing I remember of it was me saying, "I really like her, she is fun to bounce around." Not sure who "her" was.
