Do you believe in invisible beings or spirits?

Yup I do.

Like ghosts? No.

The forces of evil do exist.... I knew that... from personal experience...long before I came to God.... and God's angels are out and about the Earth.... but "ghosts"... as in departed humans coming back for visits... or sticking around haunting..... that does not happen....... when the soul leaves the body it is a one way trip.... there is no communication with the departed

I have seen the impact invisible beings can have.

Yes we Muslims believe in the species of Jinn and Angels which we humans cannot see. The animals can see the jinns though. Satan is a jinn for example, not a fallen angel, since angels have no free will and obey God's every command without hesitation.

Hence you hear dogs barking at the night, basically nothing being seen there for example, or you hear strange noises in abandoned areas where jinns usually inhabit, possessions, etc all jinns.

I don't. But I am a person who doesn't believe in belief, I try to believe as little as possible, instead to consider, to wonder, etc. A lot of people just want answers they can believe in and cling to without doubt or skepticism. I'm one who is more interested in the questions! I.e. a skeptic, an agnostic.

I don't believe that the big bang just happened.

No, since I live in the real world.
