I Have Lost People I Love From Cancer

it was a little more than 1 year ago...it was my piano teacher that taught me from 2004 until 2014 (he was in a bad health at that time and passed away after a year)...one time i had a dream with him, i was playing in a concert and i was just perfect and then i sat at a table with him and we ate salad...but then i got really sick in the dream and i woke up and ran to the bathroom and puked...i almost couldn't sleep at that night... it was a nice dream but reality made it bad...
