- Any dream that worries you can be remedied by saying the nusach brought in Shulchan Aruch and Mishna Berura in front of 3 good friends. The sooner this is done, the better. (ShA – MB , )
- If you want to fast with doing teshuva, that will burn up any bad dream. In order to be effective, the fast must be on the same day as the dream [even on Shabbos]. (ShA – MB , )
- If fasting is difficult, you can redeem the dream with paying money. (MB ) LAWS OF THANKSGIVING BLESSINGS
