It is quite easy to hypnotize someone in days because you have time to develop rapport and understand what works best to induce a trance. If you are in the beginning of your hypnosis journey then this is a good place to start and I will give you some tips to help you when it comes to hypnotizing someone over a few days.

Start small
Do not try and jump straight into a handshake induction or use conversational hypnosis to convince a girl to go home with you in a crowded bar. Start small by getting your subject in a private area where there are no distractions and get them to relax and sit/lay down.

Build rapport
Keep it relaxed and have a bit of a conversation with your subject so they realise they can trust you, the best way is to ask them to close their eyes while you chat until you see their body start to relax. Once they are at this point it is time to casually put suggestion across to them.

Simple Suggestions
Keep the suggestions so simple that your subject doesn't even notice you are making them, for example:
"can you straighten your fingers slowly?" and slowly turn the question to a command "push your feet straight".
Keep the conversation flowing as you make these suggestions and you will see that they will not make objections.


The idea is to start so small that they did not even think that you where hypnotizing them so that the next time you meet their guard is already down and you can start to explore with slightly more complicated suggestions. Continue this over a few days and be sure to use exactly the same method to relax them so that it gets to a point where they will begin to relax as soon as you mention the first phrase. As you get more confident the process will become easier and easier and just by looking at a persons body language you will start to understand if they are open to suggestion.
