I'm kinda stunned that a bunch of people who spend a large amount of their time staring at information about something are amazed at the fact they then dream about that thing.
You dream about pretty much any significant data you input into your consciousness: when I learned AS2 I dreamt in code (which is strange), when I practise my Spanish I dream in Castillano, watch enough Star Trek etc etc.
Dreaming about BTC isn't going to provide you with any market prescience outside of the coincidental, it just means perhaps you are not spreading your cognitive load evenly aka "need to get a life".
Going from my own experience, I really don't know about that.
True, spend too much time with your head in Bitcoin and you will dream a complete pile of Bitcoin mince.
But some of my best investment insight ever, has come from dreams. Sometimes it is hard to distinguish the mince from the substantial however, especially since we will always tend to bend any kind of intuition that enters our head to fit our paradigms and personal biases.
Annoyingly, I often only get a strong investment intuition if I have already made a move.
I invested heavily into silver back in $30 days when it seemed it could only go up. However, despite all the positive visualisation and positive bias reinforcement that I would do by reading the sort of bullshit that Max Keiser or Mike Maloney are endlessly putting out, I then had a dream about it being an absolute nightmare investment. Being a bit of a 'Crash JP Morgan, Buy Silver' sucker, it took a while to admit to myself that the market was going to be grim, especially since it did go up a bit in short term (I ended up taking a small loss). Thus far, I took a 3% loss and saved myself a near 40% loss.
I sold 15 BTC that I bought at $100 for $350 after deciding that the market was going down. The same night, I dreamt of Bitcoin taking out $600 on Gox (that was where I checked Bitcoin price as recently as early Nov 2013). I knew immediately that I had to get heavily into Bitcoin and quick...unfortunately it took 11 days to get clearance on Bitstamp and get GBP sent and converted to USD, I still got in, and I still made thousands.
Most recently, I had a dream where Bitcoin went to $110 and this is influencing my market outlook without a shadow of a doubt....and almost every night, I am getting dreams of Bitcoin being smashed down unbelievably low, but these dreams don't really hit me as carrying weight like the other ones I described, so I am unsure if they are a kind of subconscious self-gratification of my conscious 'bearish' outlook or just faint echoes of what my subconscious mind already knows is going to happen. If I were to put 20K into Bitcoin tonight, I am sure that I would get some kind of dream that would strongly reflect the rightness or wrongness of such a move.....but since there are no guarantees that I will...I aint gonna.
and away from investment issues, I have experienced insight from dreams into things happening around me far too many times to dismiss dreaming as 100% minced up thoughts.
