Dreaming of alumni means you are anxious about upcoming graduation ceremonies confirming your completion of a sound academic career. Upon entering the next phase of your life, you will be working instead of studying. However, you are always drawn back to your school to participate in alumni functions such as professional networking and fund raising events.
In a dream, an alumnus usually represents past friendships. The reason for this is that an alumnus is someone who has graduated from the institution and moved on with their life. They may represent people from our life that we have not seen in a long time.
A dream about an alumni generally means happiness from seeing him/her again or nostalgia for those good times in the past. This might also mean that you miss a certain time period in your life and want to revisit it.
