Some type of Dendrobium?

Hello!
I recently acquired this plant from a friend's grandma, who told me it was "something like an orchid". She says it flowers from time to time and described something like it growing a flower spike whenever it blooms.
I have a suspicion it is a dendrobium, as I've seen some pictures that look similar but I'm not 100 percent. She had it in dirt, and it seemed to be doing fine, which is another reason I'm not sure what it is.
If it is an orchid, I'd like to plant it in the right media and treat it correctly, so any help is appreciated!
