What are dreams?
Dreams, thoughts, ideas - I see these as variations of seeds that may develop into visions and plans.
They break up through the surface of the soil, to meet a wide range of conditions that will determine their future. In some areas many different ideas are welcomed and supported to develop, in other areas only ideas that follow a certain pattern are welcomed. Some ideas grow up and gives large harvests, other are forgotten at once. Some are good, and some are not so good.
To me dreams, thoughts and ideas are almost similar - but not quite. I think that ideas are more aimed at solving problems that you are aware of in some way or another. Thoughts are a wider field, and in the context here I think of the process when you for example catch a dream and begin to examinate its possibilities and what it may demand in various aspects. It may also be a thought that comes to you when for example seeing something, and you begin to wonder why the thing you see was constructed in the way it was.
Dreams are a wide field, too. Here I think of dreams about things that you really would like to see take place, but in some ways understand will never take place. The dream can be more or less detailed, but you don't go into deeper thoughts about it and try to find ideas of how to realize it.
Thoughts and ideas may also come in the opposite order.
That dream suddenly became an idea that started thoughts, which were developed in a vision and a detailed plan. Now it is a travel memory.
