i feel like a lot of things about feeding as a psi vampire are misinterpreted or not spoken about, so hereās a few things iāve figured out/researched:
once you feed from a person for the first time instead of just passively taking in energy, you WILL crave energy a lot more. your body has basically taken in more energy than itās used to and itās kick-started everything. it can also trigger energetic changes which will require more energy than you needed before
once you feed, youāll also be more likely to tell different energy sources from each other easier. obviously youāll need to practice this and it will vary from vamp to vamp, but youāll most likely very quickly notice a difference in peopleās energy, as well as crowd energy at the least
thereās many different ways of feeding and youāll probably have to experiment a bit to discover what works for you. for example, i scoop up peopleās energy from their auras and pat it down into my own, while another vampire i know will imagine the personās energy seeping up into their pores. feeding can be a very individual thing and thereās no set way to do it
you NEED to feed one way or another. itās not something that you can just shut off, your body literally needs energy. without feeding youāll feel awful, fatigued, etc. so please donāt just try to stop taking in energy
you can keepĀ ābatteriesā (charged crystals) to help you refill if you canāt get any energy, but these canāt sustain you for prolonged periods of time
i hope these all helped, thereās a huge gap where there should be info on vampirism due to the whole Scary UwU stigma, and while i canāt help with sang vamps just yet iām gonna try to round up some info too
