play the piano
Well, actually the unicorn can play the piano, but not as conventionally expected with it's feet/hooves. Instead, when the piano playing mood strikes a unicorn, it does so by moving its magical horn up and down the piano and spewing magical sparkles that fall on the exact key at the exact time. The music that it creates brings the whole world joy and happiness because it is the sweetest music there is.
Unicorns do not exist, hence they cannot be "related" to anything. Of course not.
They are just called unicorns.
A group of unicorns goes by the name of a blessing. So it would be a blessing of unicorns.
Humans can not turn into flying unicorns, or can they?
No. Unicorns are fantasy creatures that do not exist in real life and the Blue Cross organization cannot sell them because of this.
No one named the unicorns so you will be the first to name them
The unicorns in your dream represent something that has a particular meaning to you. Among other things, unicorns might symbolize joy, fantasy, creativity or innocence. Exactly what they represent in your dream depends on what you felt during the dream (wonder? joy? fear?) and what the unicorns do in the dream. For example, they might represent happiness; if they run away, that would mean that you feel as if you cannot hold onto happiness. On the other hand, if the unicorns allow you to ride them, that would suggest that you feel that you have achieved happiness.

You can't. Pegasi, unicorns, and pegasus unicorns are all fictional creatures that do not exist. Additionally, you cannot change into a different creature.
Unfortunately, unicorns tend to die in captivity. Santa does bring unicorn-themed toys and gifts, but he never brings the real thing, because unicorns need to be free.
