>Can a ghost possess something that's not technically alive and has no soul?

I have gleaned the following with a little research Re: no soul
More information from you is required:

1. You can't astral project.
2. Necrotic damage still applies
3. You cannot be raised if you cease to function.
4. Immune to "Magic Jar"
5. If your body has soul hosting capability then you can be processed. Dwarven automations are said to have the capacity to carry a soul but that soul had no will over the automation.
6. If you can be "knocked unconscious" then there must necessarily be a "conscious": a mind as complex as any humanoid.
7. You cannot be resurrected
8. No dreams
9. You may not call yourself a demon, devil or genie
10. You are excluded from certain planes such as the astral plane and negative plane.
11. There is conjecture that you would be considered undead and that does make some interesting connections but I reject it as undead implied capable of dying implies life beforehand, life always contains spirit or it would be a limited chemical reaction so you cannot be turned or become undead.
