I believe dreams have meaning and I have been checking what mine mean, so far so true.
I was wondering what are the main objects and themes in your dreams?

My main objects are
Wood -usually houses
Colored glass bottles
Hidden spaces, stairs and attics

My main themes seem to be
Going up steps
Following some path

Houses often come up in my dreams, especially where I discover whole new sections to my home I hadn't known existed or masses of antiques or other valuables stored someplace that make it much bigger and more valuable than I originally thought. They're usually exciting moments of discovery and I'm always filled with gratitude...

When I was much younger, I dreamt a lot about large bodies of water - diving in or driving through water, floods, massive waves, etc. I once dreamt I was in a cottage on a beach and several dolphins leapt out of the water and came up to me at the window of the cottage... talking to me in dolphin speak :) I've also dreamt of a huge kite festival in a stadium and that type of thing.

Steps and paths are fascinating... what do usually find along the way and do they lead to any place?

Your dreams sound like they have pretty much the same as mine --spiritual guidance and direction, values

To see a dolphin in your dream, symbolizes spiritual guidance, your intellect, mental attributes and emotional trust. Utilize your mind to its capacity and you will move upward in life. Alternatively, it suggests that a line of communication has been established between the conscious and unconscious aspects of yourself. Dolphins represent your willingness and ability to explore and navigate through your emotions.

To dream that you are riding a dolphin, represents your optimism and social altruism.

To dream of antiques, represent your time honored values, tradition and wisdom. It symbolizes something genuine or proven. It also symbolizes things in your past that may be worth holding onto or worth keeping. If you do not like or appreciate antiques, then is suggests that you are moving away from outdated childhood conditioning or old modes of thinking. On a negative note, you may be discarding or rejecting something of value that you should really be embracing and heeding.

Lovely. Thank you for that. It seems to fit.
