i have been practicing a form of sense 'expansion' persay

mainly i try to teach myself how to use different senses to understand different forms of energy, basically self-induced synesthesia, basically feeling music or seeing sounds, or hearing a feeling (i string together a feeling, hand movement, with music and i can go back and think of the part of the song and basically play it back by rememering how it felt with my hands) This also tends to bring about a different translation of the song and the message they are trying to portray, which actually seems to be more accurate than just listening.

and i have noticed that to a rather large extent this seems to carry over, if not into the dream world, at least the inbetween stages.

but i dont remember my different senses being utalized in my dreams the way you described
