What is the relationship between altered states of consciousness and Dreams?

[Yusra]

Altered states of consciousness, such as meditation, psychedelics, and sensory deprivation, can induce dream-like experiences and enhance dream recall. These states alter brain activity, allowing for increased access to the subconscious mind, where dreams reside. Dreams and altered states share similarities in brain wave patterns, neurotransmitter activity, and subjective experience. By exploring altered states, we can gain insight into the neural correlates of dreaming and the subconscious mind, and potentially tap into the creative and therapeutic potential of dreams.

If am not mistaken, I think the dreams gotten from altered states of consciousness or meditation like you have said are usually called trance. And one does not really go deep into it like when dreaming.
