Oooh...I've made a few in the past...
Bonus points for anyone able to identify the films included.
I'm thinking 7. Sx/soc? Let me justify it.
I say 7 due to the color and diversity and vibrancy of your collages. Peacock feathers, butterflies, phoenixes, rainbows are all imagery that 7s choose, and you've exhibited most of these in these collages. "Are you in a hole?"--makes me think of the 7ish fear of being stuck, trapped, stagnant, or in a rut. You've used many exotic/bizzare/"cool" images--the sorts of stuff that 7s tend to like. Rebellion and freedom seem to play into this, too.
There's a level of spiritual seeking that I associate not only with 7s (and 4s for that matter), but also with the sexual instinct--yin yangs, astrology, tarot, ankhs and oms, lotuses, hands of Fatima, imagery of divine ecstasy, etc. could all point to a need for divine union. There's a cosmic and psychedelic feel, with some minor sexual imagery and certain "intense" themes--e.g., a bleeding heart, death, fire. I notice you've featured lots of people--I'm too backward to actually know all the films,* but I wonder if the people combined with the sense of multitudes is indicative of social? Hands featuring into collages is often associated with the social instinct.
There's an underlying theme of the "stellar", the heavens above, and the psychedelic. Overall, these collages make me think of what Naranjo calls "extraterrestrial, out of this world" in relation to sx7s. I'd also be willing to bet a 4-fix was likewise involved in the creation of these--how could there not be?
*I think I see something from Cleopatra, Lawrence of Arabia, Clockwork Orange, and maybe the Cabinet of Dr Caligari...also that one cartoon where the moon gets hit with a missile. Damn, I forget what it is...I've seen it though.
