Merry meet @michael9!
Congrats on your self dedication and on your meeting with the lion- that’s very exciting! 
Amber and Francisco have shared some great advice- I agree that it is also worth doing some research to learn more about this special presence. The lion could indeed be a spirit guide, or perhaps a guardian angel/spirit, a Power Animal, or a deity.
To connect with the lion again, you could try the following:

Wishing you all the best, Michael! May your lion watch over you
