Great question! It is most definitely a tricky word. The way we pronounce oneironautics is as follows:
O - like the letter
nigh - like the beginning of ‘near’
ro - like row
na - like the beginning of ‘not’
tics - like ticks
On to your next question. Most people start lucid dreaming for the sheer fun of it. (Honestly, who wouldn’t want to fly or walk through walls?) But once you get past the recreational aspects of lucid dreaming it can open up a whole new world of possibilities in discovering your inner self. Being able to wake up within your dreams can be used as a creative tool, a tactic in overcoming anxiety, a device in which you battle the onset of nightmares, etc.
