Strangling mother dream signals some struggle or division within your social circle. You need to take things a little slower. You feel you are being stepped on by others. Your dream is an omen for your persuasiveness and spontaneity. Perhaps your family life needs to be kept in check.
If you dreamt about strangling mother:
Someone who has been a close friend up to now may suddenly show signs of wanting to become even closer to you, and of wanting to make a change from being platonic to more intimate. You would be better to allow some time to elapse before taking them seriously. If this is something you would also be interested in, then it is worth hanging on.
