BABY BOTTLE: When you set the bottle down, the liquid inside could have been moving. That moving liquid could have tipped the bottle over (making the loud noise that you interpreted as a thump). Then the bottle could have rolled off of the counter onto the floor (and not yet hit the floor when you saw it falling). HAIR STROKING: On dry days, static electricity can move hair. SMOKE ALARMS: You might have defective wall switches, wall plugs, or light sockets, which, when dirty or corroded, can short and cause smoke. You might have a wire burning inside your microwave oven. Your neighbor might have smoke (perhaps a fireplace). When you walk in the room, you stir the air, and that stirred air could push fresh air in front of the smoke alarms. Once you lie down, the same air patterns resume, and the alarm turns on again. TWO FRIENDS (NO CONNECTION BETWEEN THEM) SAID THAT YOU WERE FOLLOWED BY SOMETHING EVIL (ONE CLAIMS TO BE ABLE TO TALK TO THE DEAD AND CLAIMED THAT HE TALKED TO YOUR EVIL SPIRIT, THE OTHER SENSED AN AWFUL SMELL): Obviously you have a spirit following you. However, it is not evil. Notice that the entity smells like rotten egg (which is also the smell of a burning tire), and that it sets off smoke detectors. Many spirits are desperate to communicate to living humans. This is because they want to tell people how they died, and bring to justice those who killed them (if killed). It could be that your spirit died in a car crash, and the tires burned. It could also be a house fire. Do research about anyone who died in the neighborhood, especially in a car accident (ask neighbors and research your neighborhood (for fires) on Google. Don't be surprised if you see gory visions of burned corpses. This is normal in horrible accidents and fires. The gore, the burning, the sulfur smell, etc., are not signs of evil (despite tales of brimstone in the bible and sci fi books). Don't be afraid. Most spirits are very good, just as humans are very good. Likely the spirit (which hasn't hurt you) won't hurt you or can't hurt you. It only wants to communicate, and you should make every effort to do so. Likely the spirit is destined to become an angel, and you should not harm an angel out of fear. Calm down, and find out what the spirit wants.
