Hi
Anglic6783 and welcome to CF
When that glass fell of the table did you notice a water trail behind it as sometimes the condensation under the glass can cause it to move as I have seen before.
I wouldn't call these apparitions ghost, but demons that can be sent to torment us, but greater is He (Jesus) that is in us then he (Satan) that is in the world. Here is a study I found years ago that helps to explain demons and hope it helps.
Mark 5:1-20 is the definitive passage on demon possession and its effects in the Bible. Some of the details about demons the Bible reveals in this passage are:
1. Devils want to be near dead human bodies or tombs (vs. 2, 3, 5).
2. They can cause unusual strength (vs. 3-4).
3. They can make a person unreasonable or immune to sensible persuasion (vs. 4).
4. They cause excessive crying (vs. 5).
5. They cause sadistic and masochistic behavior (vs. 5).
6. They have an affinity for heights (vs. 5).
7. They recognize Christ as "the Son of God" and appeal to Him (vs. 6-7).
8. They know they deserve torment and dread it (vs. 6-7).
9. They have names (vs. 9).
10. More than one can possess the same body (vs. 9).
11. They desire to stay in the same geographical region or "country" (vs. 10).
12. They would rather indwell an animal body than none at all (vs. 12).
13. They can cause animals to kill themselves (vs. 13).
14. They desire to be in a body when it dies (vs. 13).
15. They have a desire for water (vs. 13).
Mark 9:17-29 gives us even more details about devils:
16. They can cause dumbness and deafness (vs. 17, 25).
17. They cause rabid animal like behavior (vs. 18).
18. They can indwell from childhood (vs. 21).
19. They cause suicidal behavior (vs. 22).
20. They resist leaving a body and violently "rent" it while leaving (vs. 26).
21. There are different kinds of devils. Some have more power than others (vs. 29).
22. Some can only be removed by prayer and fasting of believer (vs. 29).
Ephesians 6:12 states Satan has a hierarchy of "devils" in his kingdom, "For we wrestle not against flesh and blood, but against principalities, against powers, against the rulers of the darkness of this world, against spiritual wickedness in high places." Thus some devils have more power and authority than others.
In Daniel 10:13 (as well as Mark 9:29) there is an example of this. "The prince of the kingdom of Persia" withstood the angel sent to explain Daniel's vision to him for 21 days. He could only break free when the angel Michael came and helped him overcome the powerful "prince." The "prince" may have been Satan, but more likely he was a very powerful devil.
Spiritually born again Christians who are indwelled with the Holy Spirit, Romans 8:9-11; 1 Corinthians 3:16; 6:19, could never have a demon possess them, but one can oppress them like that of Paul's thorn in the flesh. The Holy Spirit would not allow a demon to possess the same person He is dwelling in.
1 Peter 1:13-25; 2 Corinthians 5:17-20, God would not allow a demon to enter into one of His own as we are a new creation in Christ covered by His blood. We wage war with Satan and his demons on a daily basis, but not from within ourselves as we are of God and through Christ we have overcome them because greater is He that is in us than he that is in the world, 1 John 4:4.
Ephesians 6:10-20 we put on the full armour of God everyday in order to stand against the evil one and his demons. The believer has overcome the world of demons and nowhere in scripture does it say that one of God's own can be demon possessed
