Indeed, the sort of spells you asked about isn't possible and considered to be a fluffy / fantasy spell.
As for the other sort of spells you asked about
Many spells do work. The other spells you told us about are actually logical and have some potential. To make sure that the spell has at least some potential to work, you have to make sure that the spell is a real magick spell that is actually connected to magick and its practices.
From this post I assume that you do not know what are real magick spells and what are fantasy spells. I have posted this before, but I don't mind posting it one more time :)
Just remember that there are two types of spells:
Real magic spells - These are real magic spells that actually work for the magic practitioner if he/she casts it properly. Such spells will work for you if you know what you are doing, if you are experienced and familiar with the basics, and work better if you will choose to follow some optional traditions like : colors, planetary days and hours, moon phases, ritual tools and supplies, etc. Such spells always worked for me if they were casted properly, since they are magic spells that have potentiaby l to work,. Do not forget that this is about potnetial, and such spells really have it. By saying real magic spells i mean that these are magic spells that can be cated by magic practitioners. Such spells do not include physical changes and DNA changes, or any actual kind of transformation. This is the other sort of spells i am going to talk about.
Fluffy / fantasy spells - Such spells are not real magic spells. The magic practitioner will not be able to get results from them even if he dedicates as much energy as he can, and even if he / she follows all of the traditions and optional things. It means that they have no potential to work. No matter what the magic practitioner tries to do, and how. Such spells include : transofrmation, DNA changes, and other kind of things which can be found only in science fiction movies. You are able to avoid such spells by : personal experience, logic sense and maturity.
Shortly, every spell that is not associated to fluffy buisness or fantasy has the potential to work and let you get your desire.
The love spells section is not associated to fluff or fantasy (unless something not ordinary is included in the spell), thus - most of the ordinary love spells have the potential to wrok properly.
Firstly, remember that spell casting is different for everyone. What some would find easy, others will find quite difficult. There is no such thing as an easy spell. The best way to try your powers is to find out where your strengths are.Find out what abilites you do have or think you have, and test them through trial and error. That is the only way you will find out, and grow. Remember this growth is learning, learning is knowledge and knowledge is the basics; I suggest starting there. I started with simple cnadle spells. This is just to light a candle, channel and direct energy to get your desire and will. What I did was only after I knew something about spell casting, I have never jumped immediately to spell casting as most of the beginners here want to do. So I do not consider any spell as a "beginner" spell and also I must say that beginners should not cast spells or move to spell casting before they have a specific knowledge and experience level about the basics of the craft.
The reason there are no "beginner spells" is because all spells require a certian level of knowledge as well as an understanding of how magick/energy works and of course how to work it.
Once you learn this, then spells will come easier. If you choose not to, prepare to fail. Simple as that.
Think of it this way...in kindergarten you learned the alphabet, then the sounds, combined sounds, did a little memorization and slowly through the year learned to read.
How well would you have done if someone handed you a book and said " read this, and prepare me an essay in 3 days ". At 5....you would've cried to mommy and not been able to do it.
Magick is the same way, while it may not take you years to learn to do spells, you still need to learn how to do it before jumping head first into it.
Learn your basics (sticked post in general info section). Then, many question you have had will be probably answered.
Here's a recommended link to the basics (guide for beginners):
If you have done this, and you already know what you are doing you can start to cast spells.
Also, see tips for spell casting here (SoM's " Tips " tab, which talks about this sort of information :moon phases, materials and supplies , mental condition , planetary hours and days , colors , etc )
Not 100% possible,but,logically speaking,on the astral plane,your astral body can try to posses another physical body and oppress the astral body within it.
