Black is a mysterious color, it is also elegant. You carry the idea that the is more to you than percieves the eye, that surface level judgement of you is inaccurate. Likewise, you have rather high self esteem and feel as though you might be a handful to others at times, that's why the cube is heavy and won't budge. Likewise you have a preference of the traditional over the modern, hence why the cube is wooden. Perhaps you are slow to adopt change?
You goals are well cemented and you feel confident about them, you feel as though your goals might take you to a different stage in your life, hence the other floor.
As for the cat, cats are independent and smart. The color black appears here again, meaning you look for someone who is mysterious just like yourself. However, you want this person to be curious and interested in learning about you. Your stance on love would be that you feel as though it is there for you to take when you feel like it. Not necessarily that you've found a person, but rather that you're confident in finding said person.
