To dream of studying philosophy represents appreciation for intelligent decisions in your past. Being aware of yourself having made good choices that are of benefit to you now. Feeling glad or relieved that you made preparations for something difficult you are now experiencing.
To dream of being in class at school represent anxiety or pressure you feel about maintaining the integrity of past intelligent decisions. Worrying that you may end up losing something you worked hard to prepare for.
Philosophy dreams may appear when you are dealing with a will or trying to collect on a insurance policy.
