Is it possible to meditate in delta waves?

[The Phantom Stranger]

I know its written that delta waves are for sleep but on some places in the internet I have seen delta brainwaves being associated with deep meditation, does this mean after a certain level of experience you can meditate even in delta state?

it is possible, but not indicated, even more so in jewtube, it can have sublime programming, and you have to appropriate your brain alone in a trance instead of using a “crutch”
