Is there a way to make Spirits believable in a Non-Magic world?

I was watching a show, in which spirits, in the sense of Spirits you can summon, etc. are a common place in the world. The spirits, generally can be anything at all that is considered a spirit already. For example:

• Human Spirits
• Any Ethereal creature (this does not include Angels, as the sense of 'God' does not exist.
• Anything else.

Note that not all humans become spirits, in fact only a handful do, depending on the life they live, (it generally comes down to whether or not they do a certain something, though that something hasn't been decided yet).

I was wondering if there is any way to explain their existence through some form of nano-science, or quantum-reality shenanigans that I don't know because I'm not great at science.

If not, what is the best way to explain their existence, without the relative term 'magic'

These spirits would be a key member of the 'world' I wanted to come up with, so it needs to be believable.

P.S I'm not sure if the tags are right. Any suggestions to correct via comment would be appeciated.
