I have never run around the world 3 times

 but I have run around my garden 3 times.

I haven’t run a forest full of wolves

 but I have climbed trees in  Country Park.

I have never seen a polar bear

 but I have seen my white cat.

I have never seen a sleeping dragon

 but I have seen my dog sleeping.

I have never swam in a pool made of lava and made it out alive but I have swam  in a pool of water like a fish and got out alive.
