Dreams, some folks might say, are a way for our brains to prepare us for future high stress events. Similar to training ourselves for something knew and unfamiliar to us. Of course the high fantasy explanation is this is a vision of the future or a hidden symbol for you to discover it's meaning. Regardless, maybe get into red cross certifications or something near along that sort of thing. Not as a way to 'fix' anything about you but simply to prepare yourself for something that could easily happen right in front of you one day.
Actually I've also come to post because I've been seemingly unable to dream for years now. I've had dreams occasionally of course, mostly nightmares or less than happy affairs I think, but routine dreaming seems to elude me ever since sophomore year of high school. Any tips to get that back into my life?
