Singing to the Lord in a dream symbolizes a godly person, Ps. 30:4
If you dream of being praised by others, this warns that there is some ill-feeling and/or jealousy around you. Don’t worry - you can overcome it if you try a bit of tact.
To dream of praising someone else, means you wish that you were more like that person in some way.
To dream of giving praise to a higher power (praying), means you need to learn to let go of your worries and trust that things will work out okay in the end.
If, in your dreamt someone b praising you, it is a forerunner of being blamed for something you have done.
To praise another in a dream foretells success in the work you are doing.
