1- To be dreaming about a harvest indicates that we are going to reap the rewards of previous carc we have taken. We can create a store for ourselves by; for instance, doing good and then achieving some kind of reward later on. We are able to work hard, and in working hard we take care of the future. So, to dream of a harvest can actually have two meanings. It can mean looking back into the past and reaping the rewards, or it can mean looking towards the future in order to use what has happened previously. The other circumstances in the dream will indicate which interpretation needs to be used.
2- To be taking part in a harvest or perhaps a harvest festival, indicates that we are celebrating our own life energy that energy we have available to us to be used in achieving those dividends we feel are ours by right.
3- Any kind of a harvest represents fruitfulness and fertility; particularly spiritual.
