You might need to learn to be less dependent on others and their good will. In your personal life a dream like this one can signify that you have greatly misjudged someone around you. While you might consider them to be caring and friendly they might be much more cold hearted and callous than you think.
Dowsing something with gasoline in order to set it on fire indicates that you are willing to change yourself and forget your old ways. A dream like this one often also signifies that you desire and you are looking forward to a new beginning in a sense.
Setting gasoline on fire in a dream has different interpretations. One of the most common is that you will pull through difficult challenges and achieve your set goals despite your environment not being friendly and supportive of your endeavors.
In other interpretations setting gasoline on fire is seen as being indicative of animosity between you and another person in your personal life. It is possible that in the upcoming time your relationship with someone will get soured and this will turn into a long standing animosity.
Smelling gasoline in your dream without seeing it is a positive sign as it signifies that soon you will be freed from a great concern of yours in real life. You might see that your reasons for being concerned were not valid in the first place.
