I am currently making an attempt at having lucid dreams. It's something that I've been interested in ever since I had one by accident when I was much younger. For those who don't know, a lucid dream is one where the person dreaming is aware that they are dreaming. The factor that makes lucid dreaming so fascinating is that you can change the content of the dream 'on-the-fly' and turn it into your own playground
So far in my life I have only ever had one lucid dream, but I only recently started practicing. One of the most important elements of practicing to lucid dream is to keep a note of what dreams you have every night. Many people call this a dream journal but I don't think this is an accurate term as it suggests that the contents of a dream journal would have some level of reflection, or alternatively, a mechanical style of logging data. I imagine some people add reflective notes to the written accounts but for me that seems like an entirely foreign idea. I don't have the time to reflect on my dreams as I forget them almost instantly from when I wake. If I don't write them down within the first two minutes I know I won't remember them.
But that doesn't mean I write my dreams like simple pieces of data. One of the things I've started to notice is that I have been using more descriptive words to explain them. For instance I had an eerie dream just nights ago which felt wholly ethereal to me; there were beings present in the dream which seemed otherworldly. Within another dream, I witnessed something get redintegrated (made whole or restored after being damaged). In one of my notes I use the word 'lassitude' but the rest of my writing is incoherent due to my poor handwriting. These aren't words I use in daily life, they're words that I know but they are words I forget about more so than not. The only reason I used words like that to describe my dreams was because the usual words would not suffice.
The more I write them down, the more outlandish and uncommon words I find myself using, and the best thing about it is that it's influencing my career. Many times us copywriters will be given a task by a client which leaves us feeling incapable. For the most part, we feel this because we do not have the knowledge to fulfil the work, we don't have the time, or we don't know how to put the brief into words. These are all problems I've run into in the past, but recently I haven't struggled so much with putting client briefs into words. Writing an account of my dreams hasn't just made me use different words, it has also made me think about the way I structure my texts. It made me recognise that I used to focus too hard on chronology rather than relevance. Keeping an account has made me switch up my styles of writing and has overall made me more versatile.
I imagine writing a constant account of your dreams would help immensely with creative writing but it also helps with non-fiction work. The thing is, the changes in writing you'll notice won't be massive. If anything, the biggest thing you might experience is that it becomes much easier to be relevant and succinct in your writing.
I write my dreams by hand because the light from a screen hurts when I wake, but typing them up works too. Some people use a Dictaphone or voice recording app too which will also be just as effective. The Subreddit r/lucidDreaming is a great place to check if you're also interested in lucid dreaming.
