Dream is one of those crazy English words with multiple meanings which are often nuanced and even perhaps in opposition to each other.
When Martin Luther King Jr. gave his famous "I have a dream" speech or Barack Obama wrote about the dreams of his father, they were undoubtedly talking about different dreams from each other and definitely referring to dreams different than the ones we have at night.
We might have dreams for our future, dreams of things we might like to acquire, or dreams of relationships we'd like to be involved in. We can idly dream in consciousness during the waking times while subconsciously dreaming with the peculiar vision of sleep. Are any of these dreams connected?
Do your practical dreams of what you would like to see in your life ever manifest themselves in the dreams of sleep? Does your fanciful daydreaming ever influence your subconscious dreaming? Do you think that subconscious dreaming can help bring desires of your mind to fruition? If so, how so?
