Many thanks for teaser music and other great input. The sound tasks from now on will be divided by element.
What kind of soundscape could the space swimming have as a background? The sequence is dream-like and it would be ideal for the soundscape to have water like qualities, but it doesn't have to be literally underwater.
How about the transfer of the alien soul to another being? Perhaps it could be a signature like sound that could be repeated together with a Point-of-view shot to the eyes of the next avatar.
P.S. "Alien soul transfer" is no longer needed. See revised script ideas.
Could that one fit?
For the opening (or other) Open space, some "things" floating past, moving close to alien as it slowly swims away, the breathing? / water strokes (muted) can be heard close to its body around 60 seconds in, followed by a fall to (wherever) its going. silence then landing in the distance - which distorts, need to fix that :-)
Heres an initial design test, theres many elements here, since the timing isnt known I aimed for 10 seconds, if the sequence is more subtle, the high frequency content needs lowering with perhaps more emphasis on the water and a final scream "glup" sound? The leaving the last body part may also need some more attack, followed by a dream like transition period and wet sounding glup as the alien enters the new body.
