That is part of your ego's defense mechanism to cling to your sense of normality by rejecting foreign concepts that do not fit your world view.
Your story does sound pretty far fetched...
If trans-dimensional beings existed then they certainly wouldn't exist materially. They would have no mass...
If an alternate dimension exists simultaneously with ours then only subatomic particles joined by quantum entanglement would be able to affect one-another without existing in a state of superposition. Should multiple dimensions exist, the subatomic fabric between them would be the only connection.
Something like a lamp being cast off of a table by itself might possibly be explained by a rare quantum entanglement. An object with mass will not move without a force strong enough to overcome inertia and friction. If for instance; one of the subatomic particles composing a proton in the lamp had an entangled twin which wound up in large particle accelerator or massive cosmic energy discharge of some sort. I imagine enough energy might be released when that proton explodes randomly... Weird stuff like that happens sometimes and there really isn't a good explanation for it.
More is possible than what meets the eye. There truly are no limits to what the universe is capable of, the reptilian shapeshifter theory is astonishingly accurate from my own witness of one. Whether or not they truly hold a reptilian or humanoid form, I don't know, though I'm sure they could take form of any being more or less. Though the concept of the reptilian theory stems from the rear part of the brain, like a reptile, our primitive instinct of fear that has highly evolved in some beings.
They try to hide how powerful our mind truly is, for if we do not know our full potential we will forever be open and submitting to superior being's control over our minds.
The only link between those two are that completely normal and healthy people whom encounter them are labeled and drugged by doctors that are unknowingly (or knowingly) fulfilling the agenda of the aliens that enslave them.
Something you should understand is that psychiatry is based off absolutely zero scientific facts or evidence. It is completely formidable conjuncture used to control the way our population thinks. The Nazis did the same thing.
Every year, a new, grossly larger volume of the DSM is released that further gives doctors ability to misdiagnose and 'treat' (profit) off of just about anyone they could imagine.
Rather than helping you solve problems and helping you gain healthier lifestyle choices and patterns, they would rather feed you pills and profit off of your defecation.
If you research mass shootings and the actual side effects of psychiatric drugs, you'll find that most every shooter had taken some form of antidepressant or other psychiatric 'medicine' before.
Have you ever wondered why antidepressants cause suicidal thoughts? We are messing with nature which has perfected an equilibrium over millions of years. We take compounds that occur naturally in plants and modify them and synthesize them as to patent and profit off of them.
The pharmaceutical industry is a huge powerhouse in maintaining the gross suffering of humanity. Their drugs kill more than all illegal drugs combined x10. Chemotherapy kills more people of radiation than it heals of cancer.
Their goal is to withhold the truth that we control our health. A positive mind will lead to a positive, healthy body. And vice versa.
It's time we abandoned our preconceived notions we were indoctrinated with. The truth is much more spiritual, empowering and liberating than those in power would ever lead you to believe.
If we all knew the truth, they would have no power. That is why people are serving lifetime sentences in prison for possessing or even admitting to possessing LSD, which is less toxic than vitamin c and was highly accepted and looked up upon as a promising therapeutic aide when it was released publicly under the trade name Delysid.
Psychedelics are the least harmful drugs, yet hold the highest punishments by law. They occur naturally around the planet, have so for millions of years and were accepted for nearly the entirety of that time frame. They even occur naturally in your brain. It is only recently that they have been demonized to keep the truth hidden from us.
