So I was doing some thinking, and I read the Egyptions had a myriad of Gods including Lion headed ones, I found that interesting.
Then I thought a bit more about it, personally I am a Christian and in our religion God states with God anything is possible, so surely bringing Nala into the physical dimension shoud be possible, then She crosses the boundaries over imagination into reality, I hope that if Christianity turns out to be correct out of all the possible universal explanations people have; that I can summon Nala into our world.
